TEACHING BASICS OF THE DESCRIPTIVE GEOMETRY – RELATIVE POSITIONS OF LINES AND PLANES

Abstract

The paper presents applications developed for teaching descriptive geometry. The purpose of the applications is represented by the understanding of the basic elements of the descriptive geometry – the lines and the planes and their relative positions in space. The applications are focused on the line contained in a plane, this item being very important for the other relative positions of a line and a plane – the line concurrent with a plane and the line parallel to a plane.
