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.
The symbol to indicate perpendicular is an up-side-down capital T. where l1 and l2 are lines m1 and m2 are slopes To find a negative reciprocal of a number, flip the number over (invert) and negate that value. These lines are perpendicular.Their slopes (m) are negative reciprocals.he symbol to indicate perpendicular is an up-side-down capital T. where l1 and l2 are lines m1 and m2 are slopes.
