Angle Angle Side Postulate
Proving Congruent Triangles with AAS
The Angle Angle Side postulate (often abbreviated as AAS) states that if two angles and the non-included side one triangle are congruent to two angles and the non-included angle of another triangle, then these two triangles are congruent.Practice Proofs
