Answer
Perpendicular line is two lines that intersect each other at 90° and parallel lines are two lines that lie on the same plane but can never intersect each other at any point.
Work Step by Step
A pair of lines is said to be perpendicular when they intersect each other at 90°. Perpendicular lines always form a right angle at their point of intersection.
A pair of lines is said to be parallel when they never intersect each other at any point. The distance between these lines always remains constant.
Thus, it can be concluded that the concept of perpendicular line and parallel line too different from each other.
