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.
But when it is perpendicular to two lines (where they intersect) then it is perpendicular to the table: It can't point anywhere else but directly away from the table. So we can say this: When a line is perpendicular to two lines on the plane (where they intersect), it is perpendicular to the plane. It will also be perpendicular to all lines on the plane that intersect there. And there is a lot more we can say:
