Lines that are parallel must not intersect at any point and they must be coplanar.
Parallel lines are important in discussions of Euclidean 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-Euclidean geometries allow for an infinite number of or no parallel lines.
