Angle reference calculator.

The reference angle is the angle that the given angle makes with the x-axis. When the terminal side of the given angle is in the second quadrant (angles from 90° to 180°), our reference angle is calculated by subtracting the given angle from 180 degrees. So, you can use the formula below: Thus, the reference angle of 121° = 180 - 121 = 59°.Angles Calculator - find angle, given angles Find the reference angle for 1500°.
