Front

What is a coterminal angle?

Back

Coterminal angles are angles that share the same terminal side when drawn in standard position. They can be found by adding or subtracting multiples of 360 degrees.

Front

How do you find a negative coterminal angle?

Back

To find a negative coterminal angle, subtract 360 degrees from the given angle until the result is negative.

Front

What is the coterminal angle of 165 degrees?

Back

-555 degrees is a negative coterminal angle of 165 degrees.

Front

What is the coterminal angle of 45 degrees?

Back

405 degrees is a coterminal angle of 45 degrees.

Front

How do you convert a positive angle to a negative coterminal angle?

Back

Subtract 360 degrees from the positive angle until the result is negative.

Front

What is the standard position of an angle?

Back

An angle is in standard position when its vertex is at the origin and its initial side lies along the positive x-axis.

Front

What is the measure of -390 degrees in standard position?

Back

-390 degrees is coterminal with 270 degrees.

Front

How do you sketch an angle in standard position?

Back

Start at the positive x-axis, rotate counterclockwise for positive angles and clockwise for negative angles.

Front

What is the relationship between angles of 360 degrees and coterminal angles?

Back

Angles that differ by multiples of 360 degrees are coterminal.

Front

What is the formula to find coterminal angles?

Back

Coterminal angles can be found using the formula: angle ± 360n, where n is an integer.
