Converse of the corresponding angle theorems

Students will learn two different methods for proving the converse of the corresponding angle theorems: corresponding, consecutive interior, alternate interior, and alternate exterior. First, students will be shown the proof for the converse of the corresponding angle postulate, using the method of proof seen here. Then students will be asked to prove the three remaining theorems, using the same setup for each proof. After that, students will be shown the proof for the converse of the corresponding angle postulate, using the method of proof seen here. Again, students will be asked to prove the remaining theorems using the same setup for each proof.
