In 1–2 sentences, explain how the Triangle Angle Sum Theorem helps prove AAS congruence.(2 points)

1 answer

The Triangle Angle Sum Theorem states that the sum of the interior angles of a triangle equals 180 degrees. This theorem helps prove the Angle-Angle-Side (AAS) congruence criterion by confirming that if two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle, the third angle must also be congruent, ensuring that both triangles are congruent overall.
