This is an interactive activity that uses a pencil, protractor and highlighter to draw a diagram using step-by-step instructions. The end result will consist of two parallel lines cut by a perpendicular transversal with a right angle bisected by an additional transversal to demonstrate the angles formed when a right angle is bisected. I used this activity with my special education geometry class and they loved it. While they worked on it individually, I was able to circulate around the class to check their progress and understanding. Because each students diagram will be different, there is no answer key included.
