Lesson 3.4 Notes and Practice:

Proofs with Parallel Lines

This lesson discusses various theorems relative to parallel and perpendicular angles theorems: linear pair perpendicular theorem, perpendicular transversal theorem, lines perpendicular to a transversal theorem. I solve problems where we try and find the distance between a point and a line as well as solving problems where we try and prove lines are parallel using the 3 perpendicular theorems discussed earlier in the lesson.
