Triangle Congruence Theorems Explained: ASA, AAS, HL

Join us as we explore the five triangle congruence theorems (SSS postulate, SAS postulate, ASA postulate, AAS postulate, and HL postulate). By the end of this lesson, you will be able to identify each theorem and understand which scenarios they can be applied in. (hypotenuse leg, angle angle side, angle side angle, side angle side, side side side)

Oh yeah, and you'll learn to avoid the donkey theorem :)
