SUMMARY
The shortest distance between two skew lines is determined by a vector that is perpendicular to both lines. This distance can be calculated using the formula d = |\vec{V} \cdot \hat{n}|, where \vec{V} is the vector displacement between points on each line, and \hat{n} is a unit vector derived from the cross product of the direction vectors of the lines. The discussion emphasizes that arbitrary points do not yield the shortest distance; instead, the perpendicular vector must be utilized to accurately measure the distance between the lines.
