Objections:

 * Define inscribed angle and intercepted arc
 * Develop and use the inscribed angle theorem and its corollaries.

Definitions:
and whose sides are cords of the circle.
 * **Inscribed angle:** An angle whose vertex lies on a circle

Theorems:
circle is equal to one half the measure of the intercepted arc. semicircle, then the angle is a right angle. arc, then they have the same measure.
 * **Inscribed angle theorem:** The measure of an angle inscribed in a
 * **Right-angle corollary:** If an inscribed angle intercepts a
 * **Arc-intercept corollary:** if two inscribed angles intercept the same

Cases:
Case 1: Vertex is on the circle. Case 2: Vertex is in the circle. Case 3: Vertex is outside the circle.
