Find Measures of Inscribed Angles Using Central Angles

This video tutorial explains the central angle theorem, which states that the measure of an inscribed angle is half of the measure of the central angle. It covers three cases of the theorem, demonstrating how to calculate inscribed angles using isosceles triangles and supplementary angles. The video also clarifies the difference between arc major and arc length, and concludes with an example calculation of an inscribed angle from a given central angle.
