In [10] the third author has determined the geodesic curves, geodesic balls of H^2¡ÁR space and has computed their volume, has defined the notion of the geodesic ball packing and its density. Moreover, he has developed a procedure to determine the density of the geodesic ball packing for generalized Coxeter space groups of H^2¡ÁR and he has applied this algorithm to them. In this paper we introduce the notion of the equidistant surface to two points in H^2¡ÁR geometry, determine its equation and we shall visualize it in some cases.
