Perpendicular Length/Distance Tutorial



Perpendicular Length/Distance Tutorial
Perpendicular Length/Distance Definition:
     This is used to generate the Length of the perpendicular from point(x1, y1) to the line Ax + By + C = 0.

Length of the perpendicular Formula:

Perpendicular Length/Distance

where
              (x1, y1) is the given point,
              Ax + By + C = 0 is the given equation.

Length of the perpendicular Example:
Find the length of the perpendicular from the point (4,3) on the line x + 2y + 5 = 0.

 x1 = 4,  y1 = 3,
 A = 1,  B = 2,  C = 5

  Substitute in the formula as :

           
            Length of the perpendicular = 3

The above example will clearly illustrates how to calculate the Perpendicular Length/Distance manually.
