2.6 - Proving Angles Congruent

by Steve Dull

​Objective:

​To prove and apply theorems about angles.

​

​A theorem is a conjecture or statement that you prove true.

​

​We are going to learn and use a lot of them. I will give you a reference sheet.

​Prove it!

​

​Three More Theorems:

​Prove Theorem 2.4: "All right angles are congruent"
