Across
- 3. angles across from each other that are congruent
- 8. an angle measuring between 90 and 180
- 10. this takes if p the q and changes it to if q then p
- 17. the interior angles add up to 180 degrees
- 18. divides an angle in half
- 19. a line that has two endpoints
- 20. theories that have been proven or can be demonstrated
- 21. a triangle where each side is a different length
- 22. used in trigonometry, also means "next to"
Down
- 1. 2 lines that will never touch
- 2. the halfway mark on a line segment
- 4. an angle measuring between 0 and 90
- 5. this segment goes across a circle passing through the middle
- 6. a figure that has at least 3 sides but can have more
- 7. a location with no size or dimension
- 9. a plane figure formed by a curved line (circumference)
- 11. a line that goes infinitely in one direction
- 12. a flat surface with only length and width
- 13. the longest side in a right triangle
- 14. these measure from 0 to 360 degrees
- 15. this segment goes from the middle to the edge of a circle
- 16. a result of two lines intersecting at a 90 degree angle
