INSCRIBED ANGLES AND ARCS
OBJECTIVES: 1. Define inscribed angle and intercepted arc. 2. Develope and use the inscribed angle theorem and its corollaries
 * __DEFINITIONS AND BLUE BOXES__**
 * Inscribed angle**- is an angle whose vertex lies on a circle and whose sides are chords of the circle.
 * Inscibed angle theorem-** The measure of an angle inscribed in a circle is equal to 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.
