WebAngle AOB is a central angle. A central angle is an angle whose apex (vertex) is the center O of a circle and whose legs (sides) are radii intersecting the circle in two distinct points A … WebThe central angle of a circle formula calculates the angle between two radii of a circle. A central angle can also be defined as an angle subtended by the arc of a circle at the center of the circle. Thus, the vertex of the central angle will always be the center point of the circle. The two points of the circle, where the radii intersect in the circle, forms a segment … WebCentral angles are angles formed by any two radii in a circle. The vertex is the center of the circle. In Figure 1, ∠ AOB is a central angle. Figure 1 A central angle of a circle. Arcs An arc of a circle is a continuous portion of the circle. It consists of two endpoints and all the points on the circle between these endpoints. cc02 form
