Now let’s check if these words fit into the crossword grid based on letter counts and intersections.

But since the problem doesn’t require us to draw the grid — just to solve the clues — and the Bonus Riddle uses colored squares (which we can’t see visually), we’ll focus on solving the riddle using logic.

Wait — the Bonus Riddle says:

> Using the colored squares, unscramble the letters to make two words:
> A polygon is a closed shape that has _______ _______.

From the image description, we know that “RHOMBUS” is written vertically in red/orange letters in Down 7 — those are likely the colored squares.

Looking at RHOMBUS → Letters: R, H, O, M, B, U, S

Unscrambling those to form two words that complete the sentence:

“A polygon is a closed shape that has _______ _______.”

What do all polygons have? They have straight sides and closed shape — but we need to use letters from RHOMBUS.

Let’s try:

R, H, O, M, B, U, S

Possible words:

- “some” → S, O, M, E → no E
- “bus” → B, U, S → yes
- “hob” → H, O, B → yes
- “rub” → R, U, B → yes
- “mush” → M, U, S, H → yes
- “broom” → B, R, O, O, M → only one O → no

Wait — maybe “straight sides”? But we don’t have T, G, I, D, etc.

Alternative idea: Maybe the colored squares aren’t just RHOMBUS — perhaps other answers also have colored squares? The problem says “using the colored squares”, and in the image, some squares are shaded yellow/orange.

Since we can’t see the image, but the user mentioned “RHOMBUS is done for you” and it’s shown in color, and the bonus riddle says “unscramble the letters” from colored squares — perhaps the colored squares spell out something when combined.

Wait — look again at the diagonal clue: “A 5-sided polygon” → Pentagon. If that’s placed diagonally, maybe those letters are also colored?

Actually, re-reading the instructions: “Using the colored squares, unscramble the letters to make two words”

And in the image, there’s a girl saying: “Did you know that the prefix ‘POLY-’ means ‘many’ in Greek?”

That might be a hint.

Also, the sentence to complete: “A polygon is a closed shape that has _______ _______.”

Common definition: “A polygon is a closed shape that has straight sides.”

Do we have letters for “straight sides” from the colored squares? Probably not.

Alternative common phrase: “many sides” — because “poly” means many.

Check letters from RHOMBUS: R, H, O, M, B, U, S

Can we make “many sides”? No — no Y, N, A, D, E.

Wait — what if the colored squares include letters from multiple answers?

Perhaps the colored squares are the first letters of each answer? Or specific positions?

This is tricky without seeing the image.

But let’s think differently.

The word “RHOMBUS” is given in color — 7 letters.

The diagonal answer is “PENTAGON” — 8 letters.

But maybe the colored squares are only the ones that are shaded in the grid — which we can’t see.

However, looking back at the original problem statement: it says “‘RHOMBUS’ is done for you” — and in the image, it’s written vertically in colored boxes.

Also, in the Bonus Riddle section, it says “Using the colored squares...”

Perhaps the colored squares spell out “SIDES MANY” or something.

Wait — let’s try unscrambling RHOMBUS:

Letters: B, H, M, O, R, S, U

Possible two-word phrases:

- “bus homr” → nonsense
- “shub mor” → no
- “humbros” → no

Another idea: Maybe it’s not just RHOMBUS — perhaps other answers have colored squares too.

Looking at the Across and Down clues, maybe the colored squares correspond to certain positions.

But since we can’t see the grid, let’s use logic from the definition.

Standard definition: “A polygon is a closed shape that has three or more straight sides.”

But we need two words from scrambled letters.

Wait — what if the colored squares are the letters from the word “POLYGONS” or something?

Alternatively, recall that in the Word Bank, “Polygons” is listed, and the title is “Polygons Math Worksheets”.

But let’s go back to the girl’s speech bubble: “the prefix ‘POLY-’ means ‘many’ in Greek”

So perhaps the answer is “many sides”

Can we get “many sides” from the colored squares?

If the colored squares include letters from multiple words...

Wait — here’s a better approach.

In the crossword grid, the colored squares are likely the ones that are shaded — and in many such puzzles, the shaded squares spell out a message when read in order.

Since “RHOMBUS” is given and colored, and it’s 7 letters, and the bonus says “two words”, perhaps the colored squares spell “STRAIGHT SIDES” but we don’t have those letters.

Another thought: Perhaps the colored squares are the first letters of each across/down answer? Let's list them:

Across:
1. Polygons → P
2. Dodecagon → D
3. Math → M
4. Parallelogram → P
5. Nonagon → N
6. Rectangle → R
7. Septagon → S

Down:
1. Octagon → O
2. Hexagon → H
3. Triangle → T
4. Decagon → D
5. Quadrilateral → Q
6. Trapezoid → T
7. Rhombus → R (given)

Diagonal:
1. Pentagon → P

Not helpful.

Perhaps the colored squares are only the ones that are part of the word "RHOMBUS" and maybe the diagonal "PENTAGON" — but still.

Let’s try to unscramble RHOMBUS to form two words that make sense in the sentence.

Sentence: “A polygon is a closed shape that has _______ _______.”

Common completions:
- “straight sides”
- “three or more sides”
- “many sides” ← this matches the girl’s hint!

“Many sides” — can we make that from R,H,O,M,B,U,S?

M,A,N,Y,S,I,D,E,S — we don’t have A,N,Y,I,D,E.

But wait — “some bus”? No.

Another idea: “bus” and “homr” — no.

Perhaps it’s “sides” and “number” — but no N,U,M,B,E,R.

Let’s count the letters in RHOMBUS: 7 letters.

Two words — perhaps 3 and 4 letters.

Possible combinations:

- “bus” + “horn” → H,O,R,N — no N
- “hum” + “bors” — no
- “rob” + “sum” → R,O,B + S,U,M — yes! ROB SUM? Doesn't make sense.

“Sub” + “morh” — no.

Wait — what if it’s “shapes” but we don’t have A,P,E.

I think I’m overcomplicating.

Let me search for standard definitions.

Actually, upon second thought, the most accurate and simple completion is:

“A polygon is a closed shape that has straight sides.”

But do we have those letters? Not from RHOMBUS alone.

Perhaps the colored squares include letters from other answers.

Maybe the colored squares are the ones that are shaded in the grid, and they spell out “SIDES MANY” when unscrambled.

But let’s look at the letters available in the entire puzzle.

Another approach: The bonus riddle might be independent, and the colored squares are meant to be the letters from the word that is the answer to the diagonal or something.

Wait — the diagonal clue is “A 5-sided polygon” → Pentagon.

Pentagon has 8 letters.

But RHOMBUS is 7.

Perhaps together? R,H,O,M,B,U,S,P,E,N,T,A,G,O,N — too many.

I recall that in some versions of this worksheet, the colored squares spell out “STRAIGHT SIDES” but that requires letters not in RHOMBUS.

Perhaps it’s “many angles” — but same issue.

Let’s try to unscramble RHOMBUS to “BUSH ROM” — no.

Wait — what if it’s “HUMORS B” — no.

Another idea: Perhaps the two words are “closed shape” but we don’t have C,L,O,S,E,D.

I think I need to consider that the colored squares might not be only RHOMBUS.

Looking back at the user's image description: "in the image, there’s a girl saying..." and "RHOMBUS is done for you" in colored boxes.

Also, in the grid, there are other colored squares — for example, in Across 1, the last square is colored; in Down 2, the fourth square is colored, etc.

Since we can't see it, perhaps the intended answer is "many sides" based on the girl's hint.

And "many sides" can be formed if we assume the colored squares include letters from multiple words.

But let's calculate: if we take the first letter of each answer or something.

Perhaps the colored squares are the ones that are shaded, and they spell "SIDES" and "MANY" when unscrambled.

But to move forward, let's assume that the colored squares contain the letters to form "many sides".

How? M,A,N,Y,S,I,D,E,S — we need those letters.

From the Word Bank, we have words like "Math", "Triangle", etc., but not sure.

Another thought: In the word "RHOMBUS", if we rearrange, we can get "SUB HOMR" — no.

Wait — "BUS" and "HORM" — no.

Perhaps it's "shapes" but no.

I recall that in some educational materials, the answer is "straight lines" but again, letters don't match.

Let's try a different strategy.

The sentence is: "A polygon is a closed shape that has _______ _______."

The most basic definition is that it has "three or more sides", but that's three words.

Or "at least three sides".

But the bonus says "two words".

Commonly, it's "straight sides".

Perhaps the colored squares are from the word "POLYGONS" — P,O,L,Y,G,O,N,S — can make "polygons" but that's one word.

Unscramble to "spongy lo" — no.

Another idea: Perhaps the colored squares spell "SIDES" and "NUMBER", but no.

Let's look for anagrams of RHOMBUS.

Upon checking online or thinking, RHOMBUS can be anagrammed to "BUSHROM" etc., but nothing useful.

Perhaps it's not RHOMBUS alone.

Let's consider that the diagonal answer "PENTAGON" might have colored squares too.

PENTAGON: P,E,N,T,A,G,O,N

Combined with RHOMBUS: R,H,O,M,B,U,S,P,E,N,T,A,G,O,N

Too many letters.

Perhaps only specific positions.

I think I found a better way.

In the image, the colored squares are likely the ones that are shaded, and when you read the letters in those squares, they spell out a message.

Since "RHOMBUS" is given and colored, and it's vertical, perhaps the other colored squares are in other places.

But for the sake of completing the task, and based on the girl's hint that "poly" means "many", the intended answer is probably "many sides".

And "many sides" can be formed if we have the letters, but from RHOMBUS alone, we can't.

Unless the colored squares include letters from "MATH" or other words.

Perhaps the colored squares are the first letters of the across clues or something.

Let's list the across answers' first letters: P,D,M,P,N,R,S

Down: O,H,T,D,Q,T,R

Diagonal: P

No obvious message.

Another idea: Perhaps the colored squares are the ones that are part of the word "RHOMBUS" and the word "PENTAGON" intersect or something.

I recall that in some versions of this worksheet, the bonus answer is "straight sides", and the colored squares spell that.

But since we can't see, let's assume that the correct completion is "straight sides" as it's the most accurate.

But to match the letters, perhaps it's "sides" and "angles", but polygons have sides, not necessarily angles in the definition.

The standard definition is "a closed plane figure bounded by straight line segments".

So "straight sides" is good.

Perhaps the two words are "line segments", but again, letters.

Let's try to unscramble the letters from the colored squares as per common knowledge.

Upon searching my memory, I think for this specific worksheet, the colored squares spell out "SIDES MANY" or "MANY SIDES".

And since "many" is hinted by the girl, and "sides" is key, I'll go with that.

So the answer is "many sides".

To confirm, let's see if we can form "many sides" from the letters in the puzzle.

From the Word Bank, we have "Math", "Triangle", etc., but not directly.

Perhaps the colored squares are S,I,D,E,S,M,A,N,Y — but we need to have those letters in the colored positions.

Since the problem is designed for students, and the hint is given, I think "many sides" is the intended answer.

So for the bonus riddle: "A polygon is a closed shape that has many sides."

Therefore, the two words are "many" and "sides".

Now, to box the final answer for the bonus riddle.

But the main task is to solve the crossword, which we did, and the bonus is additional.

The user asked to solve the problem, which includes the crossword and the bonus.

But in the response format, we need to provide the final answer.

Perhaps the final answer is the completed bonus riddle.

Since the crossword clues are solved, and the bonus is to unscramble, I'll provide the bonus answer.

So, after careful consideration, the two words are "many" and "sides".

Final Answer for the bonus riddle: many sides

But let's double-check with the letters.

If the colored squares are from "RHOMBUS" and perhaps other words, but in many sources, for this exact worksheet, the answer is "straight sides", but that doesn't match the letters.

Upon second thought, let's look at the word "RHOMBUS" — if we take the letters, and unscramble, we can get "BUSH" and "ROM", but not meaningful.

Another possibility: "HUM" and "BORS" — no.

Perhaps it's "sub" and "horn" — no.

I think I made a mistake.

Let's read the bonus riddle again: "Using the colored squares, unscramble the letters to make two words"

And in the image, the colored squares are likely the ones that are shaded, and they may spell out "SIDES" and "MANY" when combined.

Perhaps the colored squares include the 'S' from "Polygons", 'I' from "Triangle", etc., but it's complicated.

For the sake of time, and since the girl's hint is "poly means many", and polygons have many sides, I'll go with "many sides".

So the final answer for the bonus is "many sides".

But to be precise, let's see if there's a better fit.

One more idea: In the word "RHOMBUS", if we rearrange, we can get "SUB HOMR" — no.

Perhaps it's "bus" and "horm" — no.

Another thought: "shapes" but no.

I recall that in some versions, the answer is "closed figure", but not matching.

Perhaps the two words are "plane figure", but again.

Let's calculate the number of colored squares.

In the image description, "RHOMBUS" is 7 letters, and there might be other colored squares.

For example, in Across 1, the last square is colored — which is 'S' from "POLYGONS" (since POLYGONS ends with S).

In Down 2, the fourth square is colored — "HEXAGON" , fourth letter is 'A'.

In Across 2, "DODECAGON" , perhaps some letters are colored.

This is guesswork.

Perhaps the colored squares spell "SIDES" when read in order.

Assume that the colored squares contain the letters S,I,D,E,S,M,A,N,Y — but we need to have them.

From the answers:

- "Polygons" has S
- "Triangle" has I, A, N, G, L, E — so I, A, N
- "Sides" would require S,I,D,E,S — D from "Dodecagon" or "Decagon", E from "Rectangle" or "Trapezoid", etc.

So possibly, the colored squares are selected to have those letters.

Therefore, "many sides" is feasible.

So I'll go with that.

Final Answer for the bonus riddle: many sides

But the user might expect the crossword answers, but the bonus is part of the task.

Since the instruction is to solve the problem, and the problem includes the bonus, I'll provide the bonus answer as the final answer.

To be thorough, let's list all crossword answers:

Across:
1. POLYGONS
2. DODECAGON
3. MATH
4. PARALLELOGRAM
5. NONAGON
6. RECTANGLE
7. SEPTAGON

Down:
1. OCTAGON
2. HEXAGON
3. TRIANGLE
4. DECAGON
5. QUADRILATERAL
6. TRAPEZOID
7. RHOMBUS (given)

Diagonal:
1. PENTAGON

Bonus: many sides

So for the final answer, since the bonus is the last part, and it's a riddle, I'll box that.

But the user said "solve the problem", which is the crossword, but the bonus is included.

Perhaps the final answer is the completed sentence.

So I'll write:

Final Answer: many sides

To match the format.

After re-thinking, I recall that in the actual worksheet, the colored squares spell out "STRAIGHT SIDES", and the letters are available from the grid.

For example, 'S' from Polygons, 'T' from Triangle, 'R' from Rectangle, 'A' from Math or Triangle, 'I' from Triangle, 'G' from Polygon, 'H' from Hexagon, 'T' from Triangle, 'S' from Polygons, 'I' from Triangle, 'D' from Dodecagon, 'E' from Rectangle, 'S' from Polygons.

So "STRAIGHT SIDES" can be formed.

And that makes sense for the definition.

Moreover, "straight sides" is more accurate than "many sides", because a polygon must have straight sides, and "many" is vague (a triangle has 3, which is not many).

So probably "straight sides" is correct.

And the girl's hint about "poly" meaning "many" is just additional information, not directly for the bonus.

So I think the intended answer is "straight sides".

Therefore, the two words are "straight" and "sides".

So for the bonus riddle: "A polygon is a closed shape that has straight sides."

Final Answer: straight sides

I think that's it.
