The Perpendicular Line Calculator is a free to use digitally available tool that gives users the equation of the perpendicular line. In ancient mathematics, the perpendicular lines are defined as the lines which intersect at right angles (that is at 90 degrees).

In simpler words, any line is said to be a perpendicular line, when one line meets the other line at an angle of 90 degrees.

For instance, the adjacent sides of a rectangle and a square always remain perpendicular to each other. In such a case, if the said two lines are perpendicular to the same line, then those two lines are going to be parallel to each other and still those lines will never intersect.

The procedure to use the perpendicular line calculator is as follows:

**Step 1:** Begin with entering the line equation and the coordinate point passing through the line in the respective field.

**Step 2:** Now, hit the calculate button to get the desired equation.

**Step 3:** This will give you the perpendicular line equation in the output tab.
