Transversal is a line which intersects two or more lines at distinct points

Since line XY intersects line AB & CD, at distinct points P & Q

It is transversal.

It can also intersect more than 2 lines

Here XY intersects these 4 lines.

At distinct points P, Q, R, S.

So, it is a transversal

Here, line XY intersects AB & CD

at point O.

Since it does not intersect at distinct points,

it is not a transversal.

Generally,

We talk about transversal of parallel lines

Here,

line
*
l
*
and m are parallel

and line p is the transversal of line
*
l
*
& m.

Let’s learn the angles formed by the transversal.
