How are all paths that have a displacement of zero similar?

Answer:

All paths with a displacement of zero share the characteristic that the starting position and the ending position are the same. Regardless of the distance traveled or the complexity of the path taken, if the object returns to its original point of origin, the net change in position (displacement) is zero.
