How Do You Find the Measure of an Angle Created by Intersecting Chords in a Circle?

Note:

This tutorial shows you how to use your knowledge of intersecting chords in a circle to find a missing angle measurement.

Keywords:

intersecting chords

circle

angle

intercepted arcs

Background Tutorials

Use the constructions of congruent segments, congruent angles, angle bisectors, and perpendicular bisectors to make conjectures about geometric relationships

Vertical angles have a very special quality. They are always congruent to one another! Check out this tutorial to learn about and see how to identify vertical angles!

Further Exploration

Apply theorems about circles, including relationships among angles, radii, chords, tangents, and secants, to solve non-contextual problems
