# Betweenness relation and isometric imbeddings of metric spaces

Abstract

We give an elementary proof of the classical Menger result according to which any metric space X that consists of more than four points is isometrically imbedded into $\mathbb{R}$ if every three-point subspace of X is isometrically imbedded into $\mathbb{R}$. A series of corollaries of this theorem is obtained. We establish new criteria for finite metric spaces to be isometrically imbedded into $\mathbb{R}$.
