Answer 1

$\underset{–}{\text{Parallel lines:}}$
Two or more lines that lie in the same plane and never intersect each other are known as parallel lines.

Let us visualize it using a figure.
In the above figure, the pair of lines are parallel to each other as they are at a constant distance $d$ from each other, i.e. the given lines will never meet each other no matter how long we extend them.
