Geometry – Proofs using CPCTC

1.) Click to print the worksheet

2.) Watch video using worksheet

 

3.) Take the quiz

For some peculiar reason, many students seem to dislike proofs. How could I blame them for that? Thankfully, we've created a video introducing the concept of CPCTC, or Corresponding Parts of Congruent Triangles are Congruent. We then tackle a triangle proof using it. YAY MATH!
