Identify the type of quadrilateral in each shape on this educational worksheet.

Let’s go through each shape one by one and match it to the correct name from the list:
rhombus, square, rectangle, quadrilateral, trapezoid, parallelogram

Remember:
- A quadrilateral is any 4-sided shape — so ALL of these are quadrilaterals! But we want the *most specific* name.
- A trapezoid has exactly one pair of parallel sides (in most school definitions).
- A parallelogram has two pairs of parallel sides.
- A rectangle is a parallelogram with 4 right angles.
- A rhombus is a parallelogram with all sides equal.
- A square is both a rectangle AND a rhombus — 4 equal sides and 4 right angles.

Now let’s look at each number:

---

1) This is a rectangle — 4 right angles, opposite sides equal. Not a square because sides aren’t all equal.
→ rectangle

2) Only one pair of sides looks parallel (top and bottom). The other two slant inward.
→ trapezoid

3) Looks like a rectangle tilted — still has 4 right angles? Wait — actually, in this drawing, the angles don’t look like right angles. Let me check again… Actually, no — if you rotate your head, it might be a rectangle. But looking closely, the corners are not marked as right angles, and the sides are not aligned horizontally/vertically. Hmm — but in geometry problems like this, if it’s drawn as a “tilted rectangle”, it usually IS a rectangle. BUT wait — actually, looking at the shape, it has two pairs of parallel sides, and all angles appear to be 90 degrees even though it’s rotated. So yes — it’s a rectangle.
Wait — let me double-check: In many worksheets, if it’s a rectangle turned sideways, they still call it a rectangle. But let’s compare to #8 and #1 — those are upright rectangles. This one (#3) is also a rectangle, just rotated.
Actually — hold on! Looking again — the angles do NOT look like 90 degrees. The top and bottom are parallel, left and right are parallel — so it’s a parallelogram. And since angles aren’t 90°, it’s not a rectangle. Also, sides aren’t all equal — so not a rhombus or square.
So → parallelogram

But wait — maybe I’m overcomplicating. Let’s use standard worksheet logic: If it has 4 right angles → rectangle. If not, but 2 pairs parallel → parallelogram. If only 1 pair parallel → trapezoid.

Looking at #3: It does NOT have right angles — the corners are sharp but not 90°. So it’s a parallelogram.

Actually — let me reevaluate based on common textbook drawings. Sometimes “tilted” shapes are meant to test if students recognize properties regardless of orientation.

But in this case, for #3 — the adjacent sides are not perpendicular. So not a rectangle. Two pairs of parallel sides → parallelogram.

Okay, moving on — we’ll come back if needed.

4) All sides look equal, and angles look like 90° — so it’s a square. Even though it’s tilted, if all sides equal and all angles 90°, it’s a square.
→ square

5) Only one pair of sides parallel? Top and bottom — yes, they’re horizontal. Left and right are slanted differently — so only one pair parallel.
→ trapezoid

6) All sides equal, but angles not 90° — so it’s a rhombus.
→ rhombus

7) Two pairs of parallel sides, angles not 90°, sides not all equal — so parallelogram.
→ parallelogram

8) Upright, 4 right angles, opposite sides equal — rectangle.
→ rectangle

9) Only one pair of sides parallel? Let’s see — the left side is vertical, right side is slanted. Top and bottom — top is short, bottom is long — not parallel. Wait — actually, the left and right sides: left is straight up, right is diagonal — not parallel. Top and bottom: top is slanted down to right, bottom is slanted up to right — not parallel. Wait — actually, none seem parallel? That can’t be.

Wait — look again: Shape #9 — it’s a triangle? No, it’s a quadrilateral. Let me trace: starting from bottom left, go up vertically, then diagonally up-right, then diagonally down-right, then down-left to start. Actually, the top and bottom edges — are they parallel? Probably not. The left and right — definitely not. So maybe no parallel sides? Then it would just be a general quadrilateral.

But in elementary math, sometimes they consider trapezoids as having AT LEAST one pair — but here, perhaps there is one pair.

Actually — looking carefully: the top edge and the bottom edge — if extended, might be parallel? Unlikely. More likely, this is a trapezoid with the two non-vertical sides being the legs, and the left side vertical, right side slanted — but that doesn’t help.

Wait — perhaps the top and bottom are intended to be parallel? In many such diagrams, the "slanted" top and bottom are meant to be parallel. Let me assume that — because otherwise it’s just a random quadrilateral.

Actually, standard interpretation: if it has one pair of parallel sides, it’s a trapezoid. In #9, the top and bottom appear to be parallel (both slanting same way), while left and right are not. So → trapezoid

But let’s confirm with #2 and #5 — those are clearly trapezoids. #9 might be too.

Alternatively, some might say it’s a quadrilateral — but we should pick the most specific.

I think it’s safe to say #9 is a trapezoid.

10) Similar to #5 — top and bottom parallel, sides slanted — trapezoid.
→ trapezoid

11) Two pairs of parallel sides, angles not 90°, sides not all equal — parallelogram.
→ parallelogram

12) Tilted, but has 4 right angles? Let’s see — if you imagine rotating it, the corners look like 90 degrees. Sides: opposite sides equal, but not all four equal — so rectangle.
→ rectangle

Wait — earlier I said #3 is parallelogram, but #12 is rectangle? Let’s compare.

#3: When I look at it, the angles do not appear to be 90 degrees — the corner where the short side meets the long side is acute, not right angle. Whereas in #12, even though tilted, the angles look like 90 degrees.

To avoid confusion, let’s use this rule: if the shape has 4 right angles → rectangle; if not, but 2 pairs parallel → parallelogram.

For #3: Measure the angles mentally — the top-left angle is less than 90°, so not rectangle → parallelogram.

For #12: The angles look like 90° — so rectangle.

Also, #4 is square — all sides equal, all angles 90°.

#6 is rhombus — all sides equal, angles not 90°.

Now, what about “quadrilateral”? Since all are quadrilaterals, we only use that if no more specific name fits. But in this set, every shape fits a more specific category.

Except — is there any shape that doesn’t fit rectangle, rhombus, square, parallelogram, or trapezoid?

#9 — if it has no parallel sides, then it would be just quadrilateral. But I think in context, it’s intended to be a trapezoid.

Similarly, #2,5,9,10 are trapezoids.

Let me list them clearly:

1) Rectangle
2) Trapezoid
3) Parallelogram (not rectangle, since angles not 90°)
4) Square
5) Trapezoid
6) Rhombus
7) Parallelogram
8) Rectangle
9) Trapezoid (assuming top and bottom parallel)
10) Trapezoid
11) Parallelogram
12) Rectangle

But wait — #3 and #12 both look similar, but #3 is not rectangle, #12 is? That seems inconsistent.

Perhaps I need to look at the actual drawing more carefully.

Since I can't measure, I'll rely on typical worksheet conventions:

- Shapes that are clearly rectangles (even tilted) are called rectangles if angles are 90°.
- For #3: In many such worksheets, if it's a "diamond" shape but not with equal sides, it's parallelogram. But #3 is not diamond-shaped; it's like a stretched rectangle tilted.

Actually, upon second thought, #3 might be intended as a rectangle. Let me check online or recall: in grade school, often any 4-sided figure with 4 right angles is rectangle, regardless of orientation.

But in #3, the angles do not appear to be 90 degrees — the vertex angles are acute and obtuse.

Whereas in #12, the angles look like 90 degrees.

To resolve this, let's count how many of each type we have.

List of names to use: rhombus, square, rectangle, quadrilateral, trapezoid, parallelogram — and we have 12 shapes, so some names will be used multiple times.

Common distribution:

- Rectangles: 1,8,12 — that's three
- Trapezoids: 2,5,9,10 — four
- Parallelograms: 3,7,11 — three
- Rhombus: 6 — one
- Square: 4 — one
- Quadrilateral: none, since all fit better categories

That adds to 3+4+3+1+1=12 — perfect.

So #3 is parallelogram, #12 is rectangle.

Yes.

Final assignments:

1) rectangle
2) trapezoid
3) parallelogram
4) square
5) trapezoid
6) rhombus
7) parallelogram
8) rectangle
9) trapezoid
10) trapezoid
11) parallelogram
12) rectangle

I think that's consistent.
