![]() Looking at a graph, a 150° angle lies in quadrant II, therefore the reference angle is θ’ = 180° – 150° = 30°. What is the reference angle for a 150 angle? ![]() ![]() The resulting angle of 150° 150 ° is positive, less than 360° 360 °, and coterminal with 510° 510 °. How do you find the reference angle of 510? 210 degrees is 30 degrees past 180, which means the reference angle is 30 degrees. Next we would calculate the reference angle. Since the angle 180° is in the third quadrant, subtract 180° from 225°. The resulting angle of 225° 225 ° is positive and coterminal with −135° – 135 °. What is the reference angle for 240 degrees?
