Finding reference angle of a negative angle

WebThe angle of 140° is a positive angle, measured counterclockwise. The angle of –220° is a negative angle, measured clockwise. But both angles have the same terminal side. If two angles in standard position have the same terminal side, they are coterminal angles. WebSince the angle 315° 315 ° is in the fourth quadrant, subtract 315° 315 ° from 360° 360 °. 360°− 315° 360 ° - 315 °. Subtract 315 315 from 360 360. 45° 45 °.
