Definition

A central angle is an angle whose vertex is at the center of a circle and whose sides are radii of the circle.

Description

Central angles are important in the study of circles and are used to define arcs and sectors. They are commonly used in problems involving circular motion and in the design of circular objects, such as wheels and gears. In mathematics education, understanding central angles helps students grasp the properties of circles and their applications, forming a basis for more advanced studies in trigonometry and calculus.
