Front

What is the relationship between the measure of an inscribed angle and its intercepted arc?

Back

The measure of the inscribed angle is equal to half the measure of its intercepted arc.

Front

Define an arc in a circle.

Back

An arc is a portion of the circumference of a circle.

Front

What is the formula to find the measure of a central angle in a circle?

Back

The measure of a central angle is equal to the measure of its intercepted arc.

Front

How do you calculate the length of an arc?

Back

Arc length = (θ/360) * 2πr, where θ is the central angle in degrees and r is the radius.

Front

What is the difference between a minor arc and a major arc?

Back

A minor arc is less than 180 degrees, while a major arc is more than 180 degrees.

Front

What is the inscribed angle theorem?

Back

The inscribed angle is half the measure of the intercepted arc.
