Use the definition of a parallellogram

A parallellogram is a quadrilateral with ||opposite sides which are parallel||

Other Definition: A parallellogram is a quadrilateral with ||opposite sides which have equal length||

Perhaps a bit overkill but I think you could multiply each vector by a rotation matrix such that 2 of the vectors terminate at points that are colinear on some line x=c making the final vector easier to identify and then multiply the resulting final vector by the inverse of the rotational matrix

I’m busy right now so I can’t work it out on paper right now to see if that works or not
