Warm Up

Warm Up. 11.6 Circumference and Arc Length. Finding circumference and arc length. The circumference of a circle is the distance around the circle. For all circles, the ratio of the circumference to the diameter is the same. This ratio is known as ? or pi.

Introduction

Introduction Circles have several special properties, conjectures, postulates, and theorems associated with them. This lesson focuses on the relationship between chords and the angles and arcs they create . Key Concepts Chords are segments whose endpoints lie on the circumference of a circle.

10.4 Inscribed Angles

10.4 Inscribed Angles. 5/7/2010. An inscribed angle is an angle whose vertex is on a circle and whose sides contain chords of the circle. Intercepted arc is an arc that lies in the interior of an inscribed angle and has endpoints on the angle. Using Inscribed Angles.

Inscribed Angle Theorem

Inscribed Angle Theorem. Page 494. The measure of an inscribed angle is half of the measure of its intercepted arc (And vice versa) Any intercepted arc is twice the measure of its inscribed angle.
