Sec. 3.2: Use Parallel Lines and Transversals

Find the measure of all numbered angles above and then make a conjecture about the other three special angle pairs: alternate interior angles, alternate exterior angle, and consecutive interior angles. What is necessary for your conjectures to be true?
