Alternate 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][color=#b20ea8]ALTERNATE EXTERIOR ANGLES[/color][/b] that are formed. [br][br]Interact with the applet below for a few minutes, then make a conjecture about AEA.
