Abstract. In this paper, we study Bertrand surface offsets by considering the dual geodesic trihedron(dual Darboux frame) of the ruled surfaces. We obtain relationships between the invariants of Bertrand trajectory ruled surfaces. Furthermore, we obtain conditions for these surface offset to be developable.
