Document Summary

Initial sides are normally half-lines that are at 0 with a vertex while holding the given half-line in place. Terminal sides are normally rotating to determine either a positive or negative angle, which can be explained by the following: "s is normally going to be in standard position. If is positive, then all of the degrees will be above . If is negative, then all of the degrees will be below . Must be in the rst quadrant i (if and only if) is between 0 and 90 . Must be in the second quadrant i (if and only if) is between 90 and 180 . Must be in the third quadrant i (if and only if) is between 180 and 270 . Must be the quadrantal angle i (if and only if) is exactly 270 . Must be in the rst quadrant i (if and only if) is between 270 and 360 .
