In the applet below, a [b]TRANSVERSAL[/b] intersects [b]2 PARALLEL LINES[/b]. [br][br]When this happens, there are 4 pairs of [b][color=#b20ea8]corresponding 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]Answer the following questions:[br][br]1. As you move the slider, you observe that _________________________________________________________.[br][br]2. [b]If a transversal intersects 2 ________________ ______________, then the [color=#b20ea8]corresponding angles[/color] are _____________________.[/b] [br][br]3. If the pink angle above measures [math]42^\circ[/math], its corresponding angle will be ____________[math]^\circ[/math]. The grey angle will be ___________[math]^\circ[/math][br][br]4. Any other observations?[br][br]5. [Challenge Yourself] How can we show that the corresponding angle property is true?[br]
