Answer:
Having multiple starting and ending points to create the same vector means keeping the length of the vector and direction same. So you can have multiple starting and ending points of a vector if their magnitude and direction are same.
Explanation:
To have same vector the magnitude and direction should match,
for example let us consider two dimensional vector a and b
vector a starts at (0,0) and ends at (5,5)
the magnitude will be 5.
vector a starts at (1,1) and ends at (6,6)
the magnitude will be 5 again and the direction will be same as vector a
so both vector have different starting and ending point but they are the same vectors as they have same magnitude and direction.
