Four More Geometry Proofs

I completed 4 more Geometry proofs. My plan is to prove most of the theorems I go through with my Geometry class for YouTube and then I will also be adding some harder proofs as well. Tell me what you think and if there are any proofs you would like to me to add.

Alternate Interior Angle Theorem



Same-Side Interior Angle Theorem



Triangle Angle Theorem



Remote Interior Angle Theorem
