An inscribed angle is an angle whose vertex lies on a circle and whose two sides are chords of that circle.
The two chords meet at the vertex on the circle and reach across to two other points on the circle, marking off an arc between them.
A central angle is an angle whose vertex is the center of a circle and whose two sides are radii. Its measure equals that of the arc it subtends.
A chord is a line segment whose two endpoints lie on a circle, or more generally on any curve. A chord through the center is a diameter, the longest possible chord.
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.
