Determining the intersection line of two planes by the computer help

Abstract

In study of the descriptive geometry, from the point of view of understanding and assimilation by students, the issue of determining the intersection line of two planes, always was found to be difficult. Starting from this, the authors present a strategy, elaborated by themselves, and an original computer program, which gives to the students the possibility to easily understand the way in which the planes that intersect can be represented in draught or in space, and, also the way of determining the intersection line of the two planes.
