Add to ORKGIn this paper, for the congruences generated by the tangents to the lines of main curvature on a surface, necessary and su⁄cient conditions that the straight lines of these congruences are preserving the lines of curvature on their focal surfaces are derived and explained. Finally, two rectilinear congruences are introduced and investigated. 1
