© 2023, University of Nis. All rights reserved.In this paper, an isomorphism between unit dual sphere, DS2, and the subset of tangent bundle of unit 2-sphere, T M̅, is represented. According to E. Study mapping, a ruled surface in IR3 corresponds to each curve on DS2. Through this isomorphism, new forms of ruled surfaces called slant ruled surfaces in IR3 were introduced. Moreover, conditions for these surfaces to be slant ruled surfaces were given. Finally, a unique q̅−,h̅− and α̅− slant ruled surfaces in IR3 were corresponded to each striction curve of natural lift curve on T M̅.
