<u>Circle Theorem vocabulary</u>
- Chord: A straight line joining two points on the circle.
- Inscribed angle: The angle formed when two chords meet at one point on a circle.
- Intercepted arc: The arc that is between the endpoints of the chords that form the inscribed angle.
<u>Inscribed Angle Theorem</u>
The measure of an <u>inscribed angle</u> is half the measure of the <u>intercepted arc</u>.
