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 hypotenuse - leg postulate 3.ab = ab reflexive property of equality 4.△abc ≅ △abd given
