Geometry Triangle Proofs and Theorems

On this lesson, we will work through several triangle congruence Geometry Proofs Examples that focus on isosceles triangles, cpctc, the base angle theorem, reflexive property, segment bisector, and the addition postulate and you will learn how to complete two column proofs and triangle congruence proofs step by step!
