Inscribed Angles

Front

What is an inscribed angle?

Back

An inscribed angle is an angle formed by two chords in a circle which have a common endpoint. The vertex of the angle is on the circle.

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 intercepted arc.

Front

What is a minor arc?

Back

A minor arc is an arc of a circle that is less than 180 degrees.

Front

What is a major arc?

Back

A major arc is an arc of a circle that is greater than 180 degrees.

Front

How do you calculate the measure of an inscribed angle if you know the measure of the intercepted arc?

Back

To find the measure of an inscribed angle, divide the measure of the intercepted arc by 2.

Front

What is the measure of an inscribed angle that intercepts a 100-degree arc?

Back

The measure of the inscribed angle would be 50 degrees.

Front

What is the angle measurement of arc AB if the inscribed angle

Back

The angle measurement of arc AB is 140 degrees.

Front

If an inscribed angle measures 23 degrees, what is the measure of the intercepted arc?

Back

The measure of the intercepted arc is 46 degrees.

Front

What is the sum of the measures of the angles inscribed in the same arc?

Back

The sum of the measures of the angles inscribed in the same arc is equal.

Front

What is the relationship between a central angle and an inscribed angle that intercepts the same arc?

Back

The central angle is twice the measure of the inscribed angle that intercepts the same arc.
