In this note, we establish an unexpected property of the centroid of a triangle. Given any triangle ABC, let P be an arbitrary point lying within the triangle. Drop perpendiculars PD, PE, PF to the sides BC, CA, AB respectively. We ask: For which point P does the product PD · PE · PF take its largest possible value? We shall show that for any triangle, PD · PE · PF takes its maximum value when P lies at the centroid of the triangle.
