WebAngle AOB forms a central angle of circle O. A central angle is an angle which vertex is the center of a circle, and whose sides pass through a pair of points on the circle, thereby subtending an arc between those two points whose angle is (by definition) equal to the central angle itself. It is also known as the arc segment 's angular distance . WebJan 3, 2016 · The radian measure θ of a central angle of a circle with radius r that is subtended by an arc of length s is defined to be θ = s r Since you were given s and r, you can solve for θ.
