CPCTC (Corresponding Parts of Congruent Triangles are Congruent) states that if two triangles are congruent, then their corresponding parts (sides and angles) are also congruent. Since we have proven that the vertical angles of the two triangles are congruent, and we used SAS to prove congruence of one triangle, CPCTC allows us to conclude that the other sides and angles are also congruent, including the side and angle needed to show that the triangles are similar. Therefore, we can state that TBX8811 is similar to TBX8811.
