Alternate Interior Angles

In the applet below, the line t is a transversal intersecting two parallel lines. When this happens, there are 2 pairs of alternate interior angles that are formed. Interact with the applet below for a few minutes, then answer the questions that immediately follow.

Copy and paste the following questions in a google doc. Then answer the questions. There are no right or wrong answers!

1) Based on your observations with the applet, what would you say about alternate interior angles? 2) Suppose the measure of the pink angle above is 134 degrees. What would the measure of its alternate interior angle be?
