Question
The applet below shows an angle and a circle centered at the vertex of the angle. You can adjust the size of the circle using the slider at the top-
left of the applet. Each tick mark along the circle represents 1 radius length (or of the circumference of the circle), and you can use these
tick marks to help you measure the subtended arc.
