There are different types of lines. 1) Vertical 2) Horizontal lines

3) Intersecting 4) Coplanar 5) Skew 6) Parallel 7) Transversal 8) Concurrent

Here, the lines l and m are intersecting lines and O is the point of intersection.

The lines l,m and n lie in the same plane so they are coplanar.

Here, lines p and q are skew lines as they both lie in two different planes.

Just remember:

The line 'l' and 'm' are parallel lines. It is denoted as

Here, line l and m are two parallel lines and 't' is the transversal as it cuts the two parallel lines in two points A and B.

Lines l, m and n intersect at point O, so O is known as the
