The '''[[distance]] between two [[Line (geometry)|straight lines]]''' in the [[plane (geometry)|plane]] is the minimum distance between any two points lying on the lines. In the case of intersecting lines, the distance between them is zero, becausewhereas the minimum distance between them is zero (atin the point of intersection); whereas in case of two [[Parallel (geometry)|parallel]] lines, itthe distance is the [[perpendicular]] distance from aany [[Point (geometry)|point]] on one line to the other line.
