### Theory:

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.
