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.
