How to calculate Perpendicular distance between a point and a line The perpendicular distance (d) of a line Ax + By+ C = 0 from a point (x1 ,y1) is given by d = | Ax1 + by1 + c|/ root (A^2 + B^2) complete explanation of formula and solved example. 1  Education. 2  Standard YouTube License.
Perpendicular Lines and Intersecting Lines. In case of a two dimensional plane, two intersecting lines are said to be perpendicular lines if they intersect at right angles. In three dimensional space, if two lines are perpendicular, the dot product of their direction rations is zero. It is to be noted that the perpendicular lines need not intersect.
