Parallel Lines cut by a Transversal

Objectives: Students will be able to… •Identify interior and exterior angles, vertical angles, corresponding, alternate exterior, and alternate interior angles

If you have two lines cut by a transversal, how many angles can be formed? What do you notice about the corresponding angles? What do you notice about the alternate interior angles? What do you notice about the alternate exterior angles? What do you notice about vertical angles? Do you think this would be true if the two lines were not parallel? Why?
