The measure of a central angle is equal to the measure of its intercepted arc.
The following diagram shows that the angle measure of the central angle is equal to the measure of the intercepted arc. Scroll down the page for more examples and solutions.
Central angle is an angle whose vertex is on the center of the circle and whose endpoints are on the circle. The endpoints on the circle are also the endpoints for the angle's intercepted arc. The angle measure of the central angle is congruent to the measure of the intercepted arc which is an important fact when finding missing arcs or central angles.
