Question

What is the congruence theorem used to prove that the two triangles are congruent?XAASOASAWNSASMINTLхY28DELL

Answer 1

In the picture, notice that the triangles XWY and ZWY have two congruent angles, and that they share the side WY.

Therefore, the congruence theorem that can be used is AAS, which stands for Angle-Angle-Side.
