Find the reference angle of each angle
WebAny angle has infinitely many coterminal angles because each time we add 360° to that angle—or subtract 360° from it—the resulting value has a terminal side in the same location. For example, 100° and 460° are coterminal for this reason, as is −260°. ... An angle’s reference angle is the measure of the smallest, positive, ... WebExample. Determine the reference angle that corresponds to each of the following angle. a) 165˚ b) 249˚ c) 328˚ Solution: a) 165˚ is in quadrant II (90˚ < 165˚ < 180˚ ) The reference angle is 180˚ – 165˚ = 15˚
