Shortest distance between two lines
Suppose L1 and L2 be the two lines in 3D, suppose P1 and P2 be two points
on L1, L2 resp. such that distance(P2-P1) is shortest distance between L1
and L2. Does vector (P2-P1) need to be perpendicular to both L1 and L2? If
so, then why? Is it true for 2D space also?
