# How do you know if two line segments are perpendicular?

A perpendicular is a line that makes an angle of 90° with another line

## Answer: If two line segments intersect at 90 degrees, then two line segments are perpendicular

A line is a figure formed when two points are connected with minimum distance between them, and both the ends extended to infinity

## Explanation:

If two lines intersect each other and make an angle of 90 degrees, then two line segments are perpendicular to each other.

If two lines are perpendicular, then the product of their slope is -1
