In the applet below, a [b]TRANSVERSAL[/b] intersects [b]2 PARALLEL LINES[/b]. [br]When this happens, there are 2 pairs of [b]SAME-SIDE INTERIOR ANGLES[/b] that are formed. [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 same-side interior angles are _____________________.[/b] [br]2) If the gray angle above measures 120 degrees, what would the measure of its same-side interior angle be?[br][br][br]3) As you moved the slider, what transformation(s) took place?
