:''This article considers two lines in a plane. For two lines not in the same plane, see [[Skew lines#Distance]].''

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