Parallel Lines Cut By Transversal (Activity )

Use this applet to explore angle relationships from parallel lines cut by a transversal. Move points A, B, and C to change the parallel lines and transversal. 

Answer the questions below on the corresponding worksheet.

1. What do you notice about vertical angles?

2. What do you notice about corresponding angles?

3. What do you notice about alternate interior angles?

4. What do you notice about alternate exterior angles?

5. What do you notice about consecutive interior angles?
