What other information do you need in order to prove the triangles congruent using the SAS

Question

Congruence Postulate?

Answer 1

In order to prove that triangles are congruent using the SAS (Side-Angle-Side) Congruence Postulate, you need the following information:

1. Two pairs of corresponding sides of the two triangles must be congruent.
2. The included angles between the corresponding sides must be congruent.

Without these two pieces of information, you cannot prove the triangles congruent using the SAS Congruence Postulate.
