In this Google Slide Show, a set of 10 instructional clip art pieces that form an instructional sequence provide an overview of properties of parallel and perpendicular lines. The remaining slide show (about two dozen slides) provides examples of specific types of angle pairs formed by parallel lines cut by a transversal. This slide show can provide a quick reference for students once you have introduced the topic of parallel lines.Use the Google Slide Show as is or copy and past individual clip
