A central angle is an angle whose vertex is the center of a circle and whose two sides are radii.
The two radii reach out to two points on the circle, marking off an arc between them.
An inscribed angle is an angle whose vertex lies on a circle and whose two sides are chords of the circle.
A circle is a basic shape used throughout mathematics. A circle is defined as a shape where every point along its perimeter is an equal distance from its center.
An angle is the figure formed by two rays sharing a common endpoint called the vertex. Its size, measured in degrees or radians, is the amount of rotation needed to align one ray with the other.
The inscribed angle theorem states that an inscribed angle is equal to one-half the central angle that subtends the same arc.
