Introduction

We have already explored several ways to prove that certain triangles are congruent (equal) by using the SSS and SAS theorems. These techniques are useful when working with triangles in real-world problems. Did you know there are even more ways to prove triangles are congruent?

You've learned two ways to prove that triangles are congruent. Are there other ways?
