Standards Addressed:
MGSE.9-12.G.C.2 Identify and describe relationships among inscribed angles, radii, chords, tangents, and secants. Include the relationship between central, inscribed, and circumscribed angles; inscribed angles on a diameter are right angles; the radius of a circle is perpendicular to the tangent where the radius intersects the circle.

Learning Targets /Success Criteria:
--I can identify and define different types of angles and arcs in a circle.
--I can identify an give precise definitions of: arc, central angle, major arc, minor arc, semicircle, inscribed angle, intercepted arc.
--I can find measures of missing central angles or arcs in a circle.
--I can identify that central angles and their intercepted arcs are congruent.
--I can identify that circles are 360⁰.
--I can identify that semicircles are 180⁰
--I can find measures of missing inscribed angles and their intercepted arcs in a circle.
--I can identify the intercepted arc for an inscribed angle.
--I know that the measure of an inscribed angle is half the measure of its intercepted arc.
--I know that the intercepted arc of an inscribed angle is twice the measure of the inscribed angle.
