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 angles in a triangle is always 180 degrees, which allows us to determine the third angle when two angles are known. By establishing that two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, we can use the AAS (Angle-Angle-Side) congruence criterion to prove that the triangles are congruent.
