## ✔ Across Answers:

5. Two angles whose sum is 180 degrees.

4. Where lines cross over a common point.

- Answer: *Intersection*
- Explanation: The point where lines meet is called an intersection.

- Answer: *Segment*
- Explanation: A line segment has two endpoints.

10. Two lines that never cross or touch.

- Answer: *Parallel*
- Explanation: Parallel lines never meet.

11. Angles that are opposite each other when two lines intersect.

- Answer: *Vertical* (Note: This refers to vertical angles)
- Explanation: Vertical angles are opposite angles formed by two intersecting lines.

13. An angle that is 1/4 of a circle.

- Answer: *Right*
- Explanation: A quarter of a circle is 90°, which is a right angle.

15. Something that has an end.

- Answer: *Endpoint*
- Explanation: An endpoint is the end of a line segment or ray.

18. The middle point.

- Answer: *Midpoint*
- Explanation: The midpoint divides a segment into two equal parts.

20. A straight path that has a beginning but not ending.

- Answer: *Ray*
- Explanation: A ray starts at a point and extends infinitely in one direction.

22. An angle that measures more than zero degrees but less than 90.

- Answer: *Acute*
- Explanation: Acute angles are less than 90°.

## 🧩 Now, let’s fill in the crossword grid with these answers.

We’ll use the clue numbers and word lengths to fit them properly.

Let’s reconstruct the grid logically.

But since we can’t see the actual image, we rely on standard crossword conventions and word lengths.

Let’s assume the following based on typical layouts and clue lengths:

Example placements (based on length and logic):

#### Across:
- 5: SUPPLEMENTARY (13 letters) → likely long across word
- 7: LINE (4 letters)
- 8: DEGREE (6 letters)
- 9: REFLEX (6 letters)
- 12: VERTEX (6 letters)
- 14: ADJACENT (8 letters)
- 16: STRAIGHT (8 letters)
- 17: HORIZONTAL (10 letters)
- 19: SYMMETRY (8 letters)
- 21: COMPLEMENTARY (13 letters)
- 23: INFINITE (8 letters)
- 24: OBTUSE (6 letters)
- 25: ANGLE (5 letters)

#### Down:
- 1: PERPENDICULAR (13 letters)
- 2: VERTICAL (8 letters)
- 3: PROTRACTOR (10 letters)
- 4: INTERSECTION (12 letters)
- 6: SEGMENT (7 letters)
- 10: PARALLEL (8 letters)
- 11: VERTICAL (8 letters) – same as clue 2? Wait — note: “vertical” here refers to *vertical angles*, not direction.
- But the word is still "VERTICAL" — so possibly reused.
- 13: RIGHT (5 letters)
- 15: ENDPOINT (8 letters)
- 18: MIDPOINT (8 letters)
- 20: RAY (3 letters)
- 22: ACUTE (5 letters)

Now check consistency.

Wait — some words may overlap.

Let’s look at key intersections.

For example:

- Clue 5 (Across): Supplementary → 13 letters
- Clue 21 (Across): Complementary → 13 letters
- These are likely long horizontal words.

Also, Clue 1 (Down): Perpendicular → 13 letters — must intersect with a 13-letter across word.

So probably:
- 1 Across is PERPENDICULAR (13 letters) — but wait, no clue 1 across.
- Clue 1 is Down, so Down 1 = PERPENDICULAR (13 letters)
- So it intersects with a 13-letter across word — maybe 5 Across?

But clue 5 is "Two angles whose sum is 180 degrees" → SUPPLEMENTARY (13 letters) — yes!

So:
- Across 5: SUPPLEMENTARY
- Down 1: PERPENDICULAR

They must intersect — so the first letter of SUPPLEMENTARY (S) should be at the start of PERPENDICULAR? No — unless the crossing is elsewhere.

Wait — better to assign positions.

But since we don't have the visual grid, we’ll list all answers and then explain how to place them.

## ✔ Final Notes

- "Vertical" appears twice: once as a direction (Down 2), and once as "vertical angles" (Down 11). Both use the same word.
- "Supplementary" and "Complementary" are both 13 letters — likely long horizontal entries.
- "Protractor" is 10 letters — matches clue 3.
- "Intersection" is 12 letters — clue 4.
- "Segment" is 7 letters — clue 6.
- "Ray" is 3 letters — clue 20.
- "Endpoint" and "Midpoint" are 8 letters — clue 15 and 18.
