In a given circle, a central angle is an angle that has its vertex on the center of the circle. The sides of any such angle each intersect the circle in exactly one point, so the angle subtends an arc of the circle. The measure of the arc that the central angle subtends is by definition equal to the measure of the central angle, and is known as the arc segment's angular distance.
