[b]Definition:[/b] [b][color=#b20ea8]Vertical Angles[/color][/b] are angles whose sides form 2 pairs of opposite rays. [br][br]When 2 lines intersect, 2 pairs of vertical angles are formed. [color=#b20ea8]One pair of vertical angles is shown below. [/color] [br][color=#888](Click the other checkbox on the right to display the other pair of vertical angles.) [/color][br][br]Interact with the following applet for a few minutes, then answer the questions that follow.

[center][b]Copy and paste the following questions into a google doc. Then answer the questions within the same google doc.[/b][/center]1) Based upon your observations, what can be said about vertical angles? [br] [br] [br][br]2) Suppose the measure of the [color=#ff00ff][b]pink angle[/b][/color] above is 140 degrees. What would be the measure of its vertical angle?
