The measure of a central angle is equal to the measure of its intercepted arc. A central angle is an angle with its vertex at the center of a circle and its sides are radii of the same circle. Examples to show how to use the property that the measure of a central angle is equal to the measure of its intercepted arc to find the missing measures of arcs and angles in given figures.
What is an Inscribed Angle? An inscribed angle is an angle with its vertex on the circle. What is the relationship between inscribed angles and their arcs? The measure of an inscribed angle is half the measure the intercepted arc. Removing book from your Reading List will also remove any bookmarked pages associated with this title.

Inscribed Angles An inscribed angle in a circle is formed by two chords that have a common end point on the circle.
Inscribed Angle Theorem: The measure of an inscribed angle is half the measure of the intercepted arc. Called Thales Theorem. The opposite angles in a cyclic quadrilateral are supplementary. In a circle, inscribed angles that intercept the same arc are congruent. Tangent Chord Angle An angle formed by an intersecting tangent and chord has its vertex "on" the circle. Angle Formed by Two Intersecting Chords.
