Definition

An angle whose vertex is the center of a circle and whose sides are radii.

Description

A central angle is an angle whose vertex is at the center of a circle and whose sides are radii of the circle. This concept is essential in understanding the properties of circles and the relationships between angles and arcs. For example, the measure of a central angle is equal to the measure of the arc it intercepts. Understanding central angles is important for solving problems related to circle geometry and trigonometry.
