Interactive Parallel Lines

Are your students struggling with the angle relationships formed when parallel lines are cut by a transversal? Check out this web-based interactive model. This prompts discovery of corresponding, alternate interior, and alternate exterior angles through measure and color coding. Angle notation is also supported in this model. Use for whole class demonstration or pair with a lab activity for 1:1 technology.
Interactive Discovery

Perhaps combine this interactive model with a reference foldable to summarize the angle relationships investigated in the AngLegs discovery.
