For parallel lines, the length of the line joining the two parallel lines or the length of the line perpendicular to both the parallel lines has the shortest distance. What is this fallacy: Perfection is impossible, therefore imperfection should be overlooked. In that case, distance will depend on where you start on the lines, as non-parallel lines will cross (distance then is 0). For parallel lines (the same angle) absolute rho difference is equal to distance between lines. A Computer Science portal for geeks. I think you might mean line segment rather than line.
