Front

Define a minor arc.

Back

A minor arc is an arc that measures less than 180 degrees.

Front

Define a major arc.

Back

A major arc is an arc that measures more than 180 degrees.

Front

What is a semicircle?

Back

A semicircle is an arc that measures exactly 180 degrees.

Front

How do you find the measure of an arc?

Back

The measure of an arc can be found using the central angle that subtends the arc.

Front

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

Back

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

Front

If the measure of arc AB is 132 degrees, what is the measure of angle ACB?

Back

The measure of angle ACB is 66 degrees.

Front

What is the formula to find the length of an arc?

Back

The length of an arc can be calculated using the formula: \( L = \frac{\theta}{360} \times 2\pi r \), where \( \theta \) is the angle in degrees and \( r \) is the radius.

Front

How do you classify an arc based on its measure?

Back

An arc is classified as a minor arc if it is less than 180 degrees, a major arc if it is more than 180 degrees, and a semicircle if it is exactly 180 degrees.

Front

What is the measure of a full circle in degrees?

Back

The measure of a full circle is 360 degrees.
