If the pair of angles are formed by two rays meeting at a point (see the superb figure below!) then it is difficult. The only way is to call one of them (angle y) a reflex or major angle, and the other (angle x) the minor angle. A B ____ y x \ ....\ .....C Otherwise, the angles can be named by using the names of the rays that form the angles, for example, if line DC meets line AB at C, (an even better figure!) D ...\ __\__ A C B then you have angle DCA to the left and DCB to the right.
