p. 191 - 200 On the geodesic torsion of a tangential intersection curve of two surfaces in R3 B. U. Dűldűl and M. Çalışkan Received: June 12, 2012; Accepted: December 7, 2012 Abstract. In this paper, we find the unit tangent vector and the geodesic torsion of the tangential intersection curve of two surfaces in all three types of surface-surface intersection problems (parametric-parametric, implicit-implicit and parametric-imp- licit) in three-dimensional Euclidean space. Keywords: intersection curve; transversal intersection; tangential intersection.
