Find the line perpendicular to the line

Based on a brief definition, perpendicularity – is a binary relationship between objects, in this case – lines. Lines (a) and (b), located on a plane, are called perpendicular if they form four equal angles at the intersection = 90⁰.

In practice, the perpendicularity of lines and planes is applied in various fields: architecture, construction, navigation, aviation. Even carrying out repairs in residential premises without using a spirit level to determine the perpendicular would be very difficult.

Perpendicular lines are recorded as follows: a b. Calculating formulas and the angle of inclination of lines passing through given points on the coordinate plane is easier with an online calculator. Enter the given parameters (x1; y1) (x2; y2) and get the ready result.
