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

The Triangle Angle Sum Theorem states that the sum of the interior angles of a triangle is always 180°, which allows us to determine that if two triangles have two congruent angles and a congruent side between them, then the remaining angles must also be congruent, proving AAS congruence.

The Triangle Angle Sum Theorem states that the sum of the interior angles of any triangle is always 180 degrees, which can be used to prove Angle-Angle-Side (AAS) congruence by showing that if two triangles have two congruent angles and a congruent side not included between those angles, then the third angle must also be congruent.

The Triangle Angle Sum Theorem states that the sum of all angles in a triangle is always 180 degrees, which can be used to establish the equality of corresponding angles between two triangles, along with the fact that their remaining angles are congruent, thereby proving AAS congruence.
