Inscribed Angle Action !!!

Angles, Circle
Recall that in a circle, an inscribed angle is an angle whose vertex lies on the circle and whose rays intersect the circle at two other points.. An inscribed angle is shown in the applet below. Drag the slider and carefully pay attention to what happens. Answer the question that will appear in the applet and the 2 questions that appear below the applet.
Additional Questions: In the applet above.... 1) If the blue intercepted arc measures 146 degrees, what would be measures of each of the five inscribed angles be? 2) If the measure of the left-most inscribed angle was 100 degrees, what would the measures of the other inscribed angles be? What would the measure of the blue intercepted arc be?
