Abstract. One special case of Arak, Clifford and Surgailis' 1993 point-based polygon models for random graphs yields an isotropic random tessellation of convex polygons, with all vertices T-vertices. It is shown that its polygon distributions coincide with those of the random tessellation determined by Poisson isotropic random lines in the plane, for which all vertices are X-vertices (cf. Fig. 4). This surprising property extends to general orientation distributions, e.g. to rectangular tessellations stemming from a two atom distribution. Applying this property, it is shown that a wide variety of distinct random tessellations obtained from these two by superposition, nesting, etc. possess those very same polygon distributions.
