"WebIt's being rotated around the origin (0,0) by 60 degrees. So if originally point P is right over here and we're rotating by positive 60 degrees, so that means we go counter clockwise by 60 degrees. So this looks like about 60 degrees right over here. One way to think about 60 degrees, is that that's 1/3 of 180 degrees. " - Formula of angle of rotation
