Parallel

Lines that are parallel do not intersect at any point.
Parallel lines are important in discussions of Euclidian geometry. A postulate of Euclidean geometry is that given a line and a point, there is exactly one line through the point parallel to the original line. Non-Euclidian geometries allow for infinite or no parallel numbers of lines.
