Match the reasons with the statements in the proof to prove that triangle abc is congruent to triangle abd, given that ab ⊥ bd, ab ⊥ bc, and ac = ad. given: ab ⊥ bd ab ⊥ bc ac = ad prove: △abc ≅ △abd 1. ab ⊥ bd, ab ⊥ bc, ac = ad perpendicular lines form right angles 2. ∠abc and ∠abd are right angles reflexive property of equality 3. ab = ab hypotenuse - leg postulate 4. △abc ≅ △abd given
