Answer 1

ASA (Angle-Side-Angle) congruence theorem.

The Triangle Angle Sum Theorem establishes that the sum of the angles in a triangle is always 180 degrees, and AAS (Angle-Angle-Side) congruence shows that if two angles and a non-included side are a certain length, then two triangles are congruent. Both of these can be used to establish conditions for ASA congruence.
