TRAINING OF CONSTRUCTING SECTIONS OF POLYHEDRON BY THE METHOD OF INTERNAL DESIGN

Abstract

This article discusses the problems of constructing sections of polyhedron by the method of internal design. To solve these problems two types of projection are used: parallel and central. Flat sections of various prisms were constructed using the method of parallel design. Central projection was applied in the constructing of flat sections of pyramids. In the considered problems, we used positionally correct, visual images of polyhedron, an algorithmic approach in constructing sections of polyhedron. The proposed approach in the construction of polyhedron to some extent allows the formation and development of spatial representation and algorithmic thinking, professional qualities of future teachers of mathematics.
