THE STUDY OF TANGENCY TO CONICAL SURFACES
Keywords:
tangent plane, tangent straight line and conical surface.Abstract
This paper aims to study the problem of tangency of straight lines and planes, with application at conical surfaces. With the help of descriptive geometry knowledge, the plane and straight lines tangent to the conical surfaces are being determined, respecting the special conditions imposed.
