Based on the side-angle-side congruent theorem/postulate, both triangles are congruent. the answers is SAS.
What is the Side-angle-side Congruence Theorem (SAS)?
The side-angle-side congruence theorem (SAS) means that two triangles have two pairs of sides that are congruent to each other with a pair of included congruent angles in between the two pairs of congruent sides of both triangles, and thus, both triangles must be congruent to one another.
The diagram shows two triangles that share a common side which is a pair of congruent sides. It also shows a pair of another congruent sides that is marked congruent.
Also, we have a pair of included congruent angles that both triangles have.
Therefore, based on the side-angle-side congruent theorem/postulate, both triangles are congruent. the answers is SAS.
