Dear student
The angle between A and B is not defined.
Let vector A = a ; vector B = b.
a+b = a-b, 2b = 0(null vector).
Hence b is a null vector and a is any possible vector.
The catch is that the null vector doesn't have a well defined direction, and hence you cannot find the angle between a and b.
