Distance between two lines is equal to the length of the perpendicular from point A to line (2). In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel.A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron.Two lines that both lie in the same plane must either cross each other or be parallel, so skew lines can exist only in three or more dimensions. The (shortest) distance between a pair of skew lines can be found by obtaining the length of the line segment that meets perpendicularly with both lines, which is d d in the figure below. Here, we use a more geometric approach, and end up with the same result. If we select an arbitrary point on either plane and then use the other plane's equation in the formula for the distance between a point and a plane, then we will have obtained the distance between both planes. Their distance is |8−1| |h5,4,3i| = 7 √ 50. If two lines are parallel, then the shortest distance between will be given by the length of the perpendicular drawn from a point on one line form another line.
