Intersecting lines
If two lines are cross each other and share a common point, then the two lines are called intersecting lines.

Here, lines \(AB\) and \(CD\) meet each other at a point \(O\). So, \(AB\) and \(CD\) are intersecting lines.
Example:
We can see that the pair of metal blades intersecting at a common point.

Parallel lines
If two lines have the same distance and never intersect at any point, then the two lines are called parallel lines.

Here, lines \(AB\) and \(CD\) do not intersect at any point. So, \(AB\) and \(CD\) are parallel lines.
Example:
We can see that the racks on the shelf parallel to each other.
