Angles inside a circle

The measure of arcs CF and ED are shown. Angles CGF and EGD are two vertical angles formed by chords CD and EF . Drag any of the points on the edge of the circle to make a conjecture about the relationship between the angle measure and the measure of the two arcs. (HINT: You may need to make a chart to record to of the angle measures to recognize a pattern)
