Final answer:
The congruence theorem that applies in this situation is the Angle-Angle (AA) congruence theorem.
Step-by-step explanation:
In this situation, the congruence theorem that applies is the Angle-Angle (AA) congruence theorem. This theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are congruent.
To use the AA congruence theorem, you must show that two corresponding angles of the given triangles are congruent. Once you have identified the congruent angles, you can conclude that the triangles are congruent based on the AA congruence theorem.
