SECTION+9.3+INSCRIBED+ANGLES+AND++ARCS

Objectives: 1. Define inscribed angle and intercepted arc 2. Develop and use the inscribed angle theorem and its corollaries


 * __DEFINITIONS AND BLUE BOXES!!__**

INSCRIBED ANGLE- Is an angle whose vertex lies on a circle whosesides are chords of the circle. INSCRIBED ANGLE THEOREM- The measure of an angle inscribed in a circle is equal to 1/2 the measure of the intercepted arc. 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.
