Introduction
Triangle Congruence: ASA and AAS

word game with words "learn" and "math" Two triangles are considered to be congruent if they have corresponding sides and angles of equal measure. Previously, you have explored the Side-Side-Side (SSS) and Side-Angle-Side (SAS) Postulates to help you determine if two triangles are congruent. Now you will explore other ways to determine congruence, such as the Angle-Side-Angle (ASA) Postulate and the Angle-Angle-Side (AAS) Theorem.
