Same Side Exterior Angles

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]SAME-SIDE EXTERIOR ANGLES[/b] that are formed.
[color=#c51414][b]Guiding Questions:[/b] [/color][br][br]1) Are [b]same side exterior angles[/b] congruent or supplementary?[br][br]2) If the gray angle above measures 110 degrees, what would the measure of its same-side exterior angle be?[br][br]3) As you dragged the slider, what transformation(s) took place?
