Abstract

In this short note, we give a new Klamkin type inequality on the triangle: for any point P inside the triangle ABC, then (x + y + z)(xK₁² + yK₂² + zK₃²) ≥ a²yz + b²zx + c²xy where x, y, z are three real numbers, a, b, c the sides of triangle ABC and K₁ = XD,K₂ = Y E,K₃ = ZF if X, Y,Z and D,E, F are the midpoints of PA, PB, PC and BC,CA,AB respectively.
