Vocab:

Inscribed angle: When two lines connect one point on the surface of a circle with two other points on that circle
Intercepted arc: an arc formed when one or two different chords or line segments cut across a circle

The Inscribed angle Theorem:

The measure of the inscribed angle is HALF the measure of the intercepted arc

Inscribed angles:

The measure of the inscribed angle is half the angle of the central angle (remember that central angles and intercepted arcs have the same measure).
