How to Find Coterminal Angles?

The coterminal angles are defined as the angles that have the same initial side and the same terminal sides. we can find the coterminal angle(s) of any angle either by adding or subtracting multiples of 360°

There are two types of coterminal angles:

  • Positive coterminal angles
  • Negative coterminal angles

Positive coterminal angles: By adding multiples of 360° to a given angle gives positive coterminal angles.

Negative coterminal angles: By subtracting multiples of 360° to a given angle gives negative coterminal angles.

Solved Example:

Find coterminal angles for 60°


Given a = 60°

Positive coterminal angles of 60° are 60° + 360°, 60° + 720°, 60° + 1080°

= 420°, 780°, 1140°....

Negative coterminal angles of 60° are 60° - 360°, 60° - 720°, 60° - 1080°

= -330°, -660°, -1020°....

Similarly, you can try the calculator to find the coterminal angles for

1) Angle 45°

2) Angle 60°
