Wyatt is trying to prove these two triangles congruent using SAS. What is the ONE additional piece of information that he needs? (Examples for what we might need to prove congruency in a different set of triangles might include Angle B is congruent to Angle X, or segment XY is congruent to segment PT)

To prove the triangles congruent using SAS, Wyatt would need to know that the corresponding sides of the triangles are congruent.
