Triangle congruence proofs examples. This is the very first criterion of congruence. A postulate is a statement presented mathematically that is assumed to be true. Take note that ssa is not sufficient for triangle congruency.

If i made a typo, please let me know. (more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.
