what is the difference between intersecting lines & perpendicular lines ??????

Two lines are intersecting if they lie on the same plane and cross each other at some point.
Two lines are perpendicular if they are intersecting (when they extended if it is necessary) to form a right angle.

when two lines cross each other at any common point then they are called intersecting lines.


if they cross each other making a right angle {i.e., 90 deg} they are called perpendicular lines.
