"Use definitions, properties, and theorems relating to circles and parts of circles such as radii, diameters, tangents, angles, arc lengths, and sector areas to solve problems."

What you'll learn

Identify central angles and determine that a central angle equals the measure of its intercepted arc
Apply the inscribed angle theorem: an inscribed angle equals half the measure of its intercepted arc
Use the corollary that inscribed angles subtending the same arc are congruent
Recognize and apply the theorem that an inscribed angle in a semicircle (subtending a diameter) is 90 degrees
