17. Statement 1 should read . Reason 4: Vertical angles Reason 5: AAS 

18. The Given statement should read and bisect each other.


19. Reason 4: ASA Reason 5: CPCTC 

20. If we prove ΔADB and ΔCDB are congruent, then we can use CPCTC to prove the sides congruent.


21.


22. To prove ΔABC is right isosceles, prove the sides congruent and the angles perpendicular. Sides: Slopes: AB: BC: AC: Therefore, , and ΔABC is isosceles. The product of the slopes is 1, so the lines are perpendicular. Therefore, ∠ACB is right.
