Across
- 2. negating the hypothesis, negating the conclusion, and switching them
- 4. any two angles whose sum is 90
- 8. two angles that are next to each other and share a common side
- 9. two angles across from each other on intersecting lines and always congruent
- 13. if a=b, then a+c=b+c
- 16. if a=b, then a/c=b/c
- 17. how much a figure will enlarge and reduce
- 19. if a=b, a-c=b-c
- 20. if a(b+c), then a(b+c)=ab+ac
Down
- 1. if a=b, then b=a
- 3. replacing the hypothesis with its negation and replacing the conclusion with its negation
- 5. if a=b, then ac=bc
- 6. a figure has point symmetry if the figure can be mapped onto itself by rotating the figure 180 about a center point
- 7. any two angles whose sum is 180
- 10. two angles that are adjacent and supplementary and they form a straight line
- 11. if the figure can be mapped onto itself by a reflection line
- 12. a figure has rotational symmetry if the figure can be mapped onto itself by rotating the figure less than 360 about a center point
- 14. exchanging the hypothesis and conclusion
- 15. an enlargement or reduction
- 18. using the given hypothesis and conclusion
