Inscribed angles of circles

In this lesson we’ll look at inscribed angles of circles and how they’re related to arcs, called intercepted arcs. A chord is a straight line segment that has endpoints on the circumference of the circle, and an inscribed angle is formed by two chords. These chords share the vertex of an angle. The arc that touches the endpoints of the chords is called the intercepted arc.

How to use the Intersecting chord theorem

A chord of a circle is a line segment that has both of its endpoints on the circumference of a circle. The intersecting chord theorem says that the product of intersecting chord segments will always be equal, so we can use this theorem to solve problems involving chords of circles.
