In the applet below, a [b]TRANSVERSAL[/b] intersects [b]2 PARALLEL LINES[/b]. [br][br]When this happens, there are 2 pairs of [b][color=#b20ea8]ALTERNATE INTERIOR ANGLES[/color][/b] that are formed. [br][br]Interact with the applet below for a few minutes, then answer the questions that immediately follow.

[color=#c51414][b]Directions & Questions:[/b] [/color][br][br]1) Complete the following statement: I[b]f a transversal intersects 2 ________________  ______________, then [color=#b20ea8]alternate interior angles[/color] are _____________________.[/b] [br][br]2) If the pink angle above measures 156 degrees, what would the measure of its alternate interior angle be?  What would the measure of the gray angle be?  [br][br]3) As you moved the slider, what transformation(s) took place?
