Look at the figure and answer the questions.

How many pairs of parallel lines are there?"

To do:

We have to find the number of parallel lines in the given figure.

Solution:

Parallel lines :

•  In geometry, parallel lines can be defined as two lines in the same plane that are at equal distance from each other and never meet.
• Parallel lines are represented with a pair of vertical lines between the names of the lines, such as AB | | CD.

Therefore,

In the given figure, $IG \parallel AE$, $AB \parallel CH$, $CH \parallel DE$ and $AB \parallel DE$.

There are 4 pairs of parallel lines in the given figure.
