Parallel Lines & Transversal Angles

I introduce the properties of angles that are formed when 2 parallel lines are intersected by a transversal. These angles include Corresponding, Alternate Interior, Alternate Exterior, and Same-Side Interior angles. I finish with 5 examples, the last of which is a proof involving parallel lines.
