Match the following statements to the reasons listed. note: in a traditional proof format, the statements would be on the left side of the proof. given: ad = bc prove: a = b 1. ad = bc, bc ⊥ ae, ad ⊥ be given 2. ∠d and ∠c are right angles cpcte 3. ∠e = ∠e reflexive 4. triangle ade congruent to triangle bce la 5. ∠a = ∠b perpendicular lines form right angles.
