Included are two days worth of notes for congruent triangle proofs. Day 1 focuses on the common postulate/theorems/definitions used in a congruent triangle proof, as well as example proofs. Day 2 focuses on using using CPCTC as a reason in a proof.
Notes are intended to be folded in half and and p

This is an activity/worksheet my students seem to enjoy: in the process of learning about CPCTC (Corresponding Parts of Congruent Triangles are Congruent), they create two copies of a shape, and then take apart parts of the shape to see that the corresponding parts are actually congruent.
Make sure
