When we have proved the two triangles in congruence through this benchmark, the remaining two sides and the third angle will also be equal. Triangle Congruence Theorems (SSS, SAS, ASA) Triangle Congruence Postulates. There are several different postulates you can use to prove that two triangles are congruent - that they are exactly the same size and shape. Two triangles are congruent if they have two congruent sides and the Menu. Their interior angles and sides will be congruent. The SSS criterion for triangle congruence states that if two triangles have three pairs of congruent sides, then the triangles are congruent. This is one of them (SSS). When two triangles are congruent, we can also say that each of their corresponding parts are congruent. Congruence Postulate SSS.
