Across
- 2. Adjacent, supplementary angles.
- 3. polygon sides are all congruent.
- 7. divides a segment or angle in two equal parts.
- 10. goes forever in all directions, two-dimensions
- 13. no dimensions, a marks a spot in space
- 14. a line that crosses two or more lines.
- 16. intersect at a right angles.
- 18. the points at an end of a line segment
- 20. transformation that "slides" each point
- 22. have the same relative positions
- 24. a transformation that turns a figure.
- 25. different planes and don't intersect
- 26. polygon angles are all congruent.
- 27. two angles whose sum is 90 degrees.
- 28. a transformation that makes a mirror image.
Down
- 1. has two endpoints.
- 4. common vertex and a common side
- 5. same plane and they do not intersect.
- 6. 2 nonadjacent angles from 2 intersecting lines
- 8. same shape but not the same size.
- 9. all its sides and angles are congruent
- 11. two angles whose sum is 180 degrees.
- 12. 1 endpoint; goes on forever in one direction.
- 15. changes the size, but not the shape.
- 17. no thickness goes on forever, one dimension
