Front

What is an angle in a circle with vertex at the center of the circle?

Back

A central angle.

Front

Define a central angle.

Back

A central angle is an angle whose vertex is at the center of the circle and whose sides are radii.

Front

Define an inscribed angle.

Back

An inscribed angle is an angle formed by two chords in a circle which have a common endpoint.

Front

What is the relationship between a central angle and the arc it intercepts?

Back

The measure of the central angle is equal to the measure of the arc it intercepts.

Front

What is the relationship between an inscribed angle and the arc it intercepts?

Back

The measure of an inscribed angle is half the measure of the arc it intercepts.

Front

If the measure of arc AB is 68°, what is the measure of the inscribed angle that intercepts arc AB?

Back

The measure of the inscribed angle is 34°.
