Notes
Pairs of Lines  Transversal:

A line that intersects two or more lines at distinct points is called a transversal.

You might have seen a road crossing two or more roads or a railway line crossing several other lines. These give an idea of a transversal.

A transversal is a line that intersects two or more lines at distinct points.

A transversal gives rise to several types of angles.

Line l intersects lines m and n at points P and Q respectively.Therefore, line l is a transversal for lines m and n.
