-Define inscribed angle and intercepted arc. -Develop and use the Inscribed Angle Theorem and its corollaries.
 * Objectives:**


 * Vocabulary:**

//**Inscribed angle:**// An angle whose vertex lies on a circle and whose sides are chords of the circle. [|This link] will show what an inscribed angle and central angles are.

//**Intercepted arc:**// The arc of a circle within an inscribed angle.


 * //Inscribed Angle Theorem://** Two or more chords that starts inside the circle to form an angle.


 * //Right-Angle Corollary://** If an inscribed angle intercepts a semicircle, then the angle is a right angle

//**Arc-Intercept Corollary:**// If two inscribed angles intercept the same arc, then they have the same measure.
