Answer
These triangles are congruent using the SAS theorem.
Work Step by Step
In these two triangles, two sides on each of the triangles are congruent. The included angles are also congruent because they form vertical angles, and vertical angles are congruent. Therefore, we can prove that these triangles are congruent using the SAS theorem, which states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then those two triangles are congruent.
