This article covers angles that have their vertex inside a circle—so-called chord-chord angles.The measure of a chord-chord angle is one-half the sum of the measures of the arcs intercepted by the angle and its vertical angle. Suddenly, the coffee machine catches on fire. This worksheet summarizes all of the angle-arc relationships in circles as well as the segment relationships in circles. The common point is called the vertex, and the two rays are called the arms of the angle. Answers for all the math worksheets and printables.
