Angle Formed by 2 Chords (V2): What Do You See?

Applet allows for students to intuitively see (without words OR angle measures) that the measure of an angle formed by 2 chords is = to the half the sum (average) of the measures of its intercepted arcs. (Students first need to recall the Inscribed Angle Theorem, which states that the measure of an inscribed angle of a circle is equal to half the measure of its intercepted arc.)
