This video discusses about the different criteria for congruence of triangles. The proof of each criteria is also explained. All the congruence rules for triangle SAS (Side-Angle-Side), ASA (Angle-Side-Angle) and its extension AAS (Angle-Angle-Side),SSS(Side-Side-Side) & RHS (Right Angle-Hypotenuse-Side) are explained here with their proofs.
