Front

What is the definition of 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 for a given angle?

Back

To find a negative coterminal angle, subtract 360 degrees from the given 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 of a coordinate plane and its initial side lies along the positive x-axis.

How do you find a coterminal angle to a given angle?

Back

To find a coterminal angle, add or subtract 360 degrees from the given angle.

Front

What is the coterminal angle of 45 degrees?

Back

405 degrees is a coterminal angle of 45 degrees.

Front

What is the formula to convert an angle in degrees to radians?

Back

To convert degrees to radians, use the formula: radians = degrees × (π/180).
