Step 1 Given The triangle are   Step 2 To determine what information need to prove triangles congruent using SAS congruence postulate . To prove SAS congruence postulate , We need to prove two sides and one angle are congregants in triangle △ACBand△ACD By using given diagram BC is congruent CD to prove △ACB=∼△ACD AC is congruent to AC, Using reflective property . In triangle ABC , AC is angle bisector of angle A and side bisector of BD By using angle bisector theorem ∠BAC=∼∠DAC. Therefore , To prove triangles congruent using SAS congruence postulate you need information ∠BAC=∼∠DAC.
