Rank the vector combinations on the basis of their angle, measured counterclockwise from the positive x axis. Vectors parallel to the positive x axis have an angle of 0 degrees. All angle measures fall between 0 and 360 degrees.
Rank from largest to smallest. To rank items as equivalent, overlap them.
