Connor is trying to prove these two triangles congruent using ASA. 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 triangles congruent using ASA (Angle-Side-Angle), Connor needs one additional piece of information - the length of a side of one of the triangles.

To prove the congruence of two triangles using the ASA (Angle-Side-Angle) criteria, Connor needs the following additional piece of information:

He needs to know that one of the angles of one triangle is congruent to one of the angles of the other triangle. In addition to the angles, he also needs to know that the corresponding sides adjacent to those angles are congruent.

Therefore, Connor needs to have the information that one angle from one triangle is congruent to one angle in the other triangle and that the side between those angles is congruent in both triangles.
