Today, on October 9th, 2008, we talked about the many different relationships between alternate exterior angles, alternate interior angles, corresponding angles, and consecutive interior angles when the transversal intersects between two parallel lines. This picture on the left is the picture that I made using geometers sketch pad and it shows the angles measurements which helps to show the relationships amongst the different angles. As well as the following slides are just from the Dyknow presentation from during class and you can use them as notes.
