Why Lesson Planet?
Learning how to prove theorems in geometry can be challenging. This resource explains what a proof is, and the different styles for proofs. It also contains links to web-based practice problems that help guide learners though example proofs. A classroom activity is also included to help in understanding the sequencing of steps in a proof. Note: Some of the image links are broken in the practice problems but the other resources still provide a good introduction to proofs.
