Parallel lines:

Two lines l and m are said to be parallel if
(i) they lie in the same plane
(ii) they do not intersect when produced indefinitely in either direction and we write l || m (which is read as 'l is parallel to m')
l || m also implies that m || l.

Transversal line:

A line which intersect two or more given lines at distinct points, is called a transversal of the given lines.
