WebAn angle’s reference angle is the measure of the smallest, positive, acute angle t t formed by the terminal side of the angle t t and the horizontal axis. Thus positive reference angles have terminal sides that lie in the first quadrant and can be used as models for angles in other quadrants. See Figure 1 for examples of reference angles for ...
