Proofs give students much trouble, so let's give them some trouble back! In this lesson we cover the four main methods of proving triangles congruent, including SSS, SAS, ASA, and AAS. We cover CPCTC as well. In the two proofs covered, one involves parallel lines and the other triangles back to back, using the reflexive property. YAY MATH!
