Across
- 1. the part of the circle between two points on the edge of a circle
- 6. 360 degrees
- 12. an angle that is less than 90 degrees
- 16. every polygon has an exterior angle sum of 360 degree
- 17. goes indefinitely in both directions
- 18. extends infinitely in only one direction
- 19. an angle thats 180 degrees
- 21. two or more lines that lie in the same plane and never intercect each other
Down
- 2. a polygon having n sides and n vertices
- 3. are 2 lines that intersect at a 90 degree angle
- 4. a arc less than 180 degrees
- 5. part of a circle formed by the radius
- 7. an angle thats 90 degrees
- 8. the area enclosed by a circle
- 9. an angle thats more than 90 degrees
- 10. is like a line except that it has two clearly defined endpoints
- 11. polygon that has all equal sides and all equal angles
- 13. is the exact middle point. It divides the line segment into two equal halves.
- 14. an arc more than 180 degrees
