This article is written for middle school students to learn about parallel lines and transversals It is brief (one page), but will give your students a chance to read about corresponding, alternate interior, alternate exterior, and vertical angles. This can be used in station rotations or with a whole class. I have included directions and activity sheets for a partner reading activity and small group summarizing.

Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles. For example, arrange three copies of the same triangle so that the sum of the three angles appears to form a line, and give an argument in terms of transversals why this is so.
