complete this sentence with the best of the choices given. according to the ____________ theorem, when two angles and the side opposite one of them in a triangle are congruent to the corresponding parts of a second triangle, then the two triangles are congruent.

Explanation:

Step1: Recall congruence criteria

The AAS (Angle - Angle - Side) criterion states that if two angles and the non - included side of one triangle are congruent to two angles and the non - included side of another triangle, the two triangles are congruent. This exactly matches the description in the question.

Answer:
