Explore Angles Inside and Outside Circles
*****Use this animation to confirm what you discovered about the relationship of angles inside and outside a circle and the 2 arcs intercepted by the sides of the angle.*****
Watch the formula at the bottom of the applet and notice how it changes when the vertex of the angle is inside the circle vs. outside the circle.
*Move Point C or D to change the size of Arc1 and Arc2.
*Move Point E to change the location of the vertex of the angle or the size of Arc 2.
