# Perpendicular Distance of a Point from a Line – Cartesian form

Foot of perpendicular from a point on the given Line: Here, the equation of line AB is . Let L be the foot of the perpendicular from P (α, β, γ) on the line . Let the coordinates of L be (x₁ + aλ, y₁ + bλ, z₁ + cλ). Then the direction ratios of Read more about Perpendicular Distance of a Point from a Line – Cartesian form[…]
