How do you find a coterminal angle?

Back

To find a coterminal angle, add or subtract multiples of 360° (or 2π radians) to the given angle.

What is a positive coterminal angle for -90°?

Back

A positive coterminal angle for -90° is 270° (since -90° + 360° = 270°).

Front

What is a negative coterminal angle for 150°?

Back

A negative coterminal angle for 150° is -210° (since 150° - 360° = -210°).
