In this paper we are dealing with coordinatization of a given affine plane d by a PTR1). Such coordinatizations were first investigated in [4]. In [5] and [6] the necessary and sufficient conditions that a PTRZ coordinatizes a translation plane, a Desarguesian plane and a Pappian plane were deduced.
