Angle Formed by Chord & Tangent (II)

In the circle in the applet below, the pink angle is said to be an angle formed by a chord and a tangent. This applet accompanies the second part of the Angle Formed by a Chord & Tangent activity sheet you received at the beginning of class. Before answering the questions on the second part of this activity, interact with this applet for a few minutes. As you do, be sure to change the locations of the BIG POINTS each time before re-sliding the slider!
