Recall that a

**CHORD**is a segment whose endpoints lie on a circle. In the applet below, note that the**purple angle**is formed when the two chords intersect. This angle formed by two chords intercepts two arcs.**One intercepted arc is red.****The other intercepted arc is blue.***Drag the green slider and carefully watch what happens.*Feel free to move any of the points of the circle around to change the location of the purple angle formed.*As you move them, make sure that the 2 chords intersect each other!*Answer the questions that follow the applet.**Please respond to the following prompt:**

*From what you've seen, describe how you believe you can find measure of an angle formed by two chords of a circle. (Be sure to use the term "intercepted arc" or "intercepted arcs" at least once in your description.*
