New inequalities for a triaugle and an internal point

  • A. Oppenheim


In this note is obtained by a simple geometrical transformation a family of inequalities which connect the distances of an internal point from the vertices of a triangle with its distances from the sides. Stronger forms of old inequalities are also found.
