In your daily life, you might have seen the street lamp, the electrical junction, and a tremendously constructed building. If you take a closer look, you might have seen a transversal lines in these constructions.

Example:

1. The electrical junction makes a transversal line.

2. The shadow of the street light makes the transversal line.

3. A well-constructed building's design.

Transversal is a line, which intersects two or more lines in different points.

Here,

$m$ and

$n$ are any two non-parallel lines and

$l$ is another line intersecting them at

$A$ and

$B$ .

Such intersecting line

$(l)$ is called as a transversal line because the line

$l$ intersects two lines at distinct points.

The line

$l$ is not a transversal to the lines

$m$ and

$n$ , but it is a transversal to the pair of lines m and

$o$ ,

$n$ and

$o$ .

Now, let us see some more lines. Observe the below two figures.

How do these images differ from the above figure?

The above figures are not a transversal line. Because the line

$l$ does not intersect the lines

$m$ and

$n$ at distinct points. So, it is not a transversal line.
