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

Answer 1

The Triangle Angle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees. This theorem supports the Angle-Angle-Side (AAS) congruence criterion by allowing us to deduce the third angle of a triangle when two angles and a non-included side are known, thereby confirming that two triangles with corresponding angle pairs and a side are congruent.
