This activity was created for middle school math stations on interior and exterior angles in triangles. As students rotate through stations, they can be challenged in individual, partner, and group activities and games. This is an individual practice station. Here, students work independently on a guided problem solving activity. It requires students to make conclusions about angle sums using transversals. I laminate the included student directions to keep at the station.

Look out for this activity and many others in my eight grade bundles at a deep discount!!! Coming Soon!

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.
