Basics of Triangle Congruence Postulates

In this video, I discuss the 5 different triangle congruence postulates: Side-Side-Side(SSS), Side-Angle-Side(SAS), Angle-Side-Angle(ASA), Angle-Angle-Side(AAS), and Hypotenuse-Leg(HL) otherwise known as Right-angle-Hypotenuse-Side(RHS). I also discuss how you can't prove 2 triangles are congruent comparing only corresponding angles (Angle-Angle-Angle or AAA). In the accompanying videos, I go over practice problems to help you understand these 5 postulates.

The video might take a little while to play. Please be patient.
