SPECIAL PROPERTIES OF THE TETRAHEDRON IN HISTORICAL DEVELOPMENT

Abstract

The article discusses one of the most pressing and at the same time difficult issues for teaching geometry, as well as for the assimilation of the properties of spatial figures by students. The authors focus on the peculiarities of the methodology for studying the main facts of the topic “Geometry of a tetrahedron”. The importance and difficulty of studying the topic are associated primarily with the versatility, abstractness, features of the images of spatial figures. The characteristic features of the introduction of these concepts are highlighted and described. Considerable attention is paid to the history of the study of tetrahedrons. The methodology for introducing the basic concepts of this topic presented in the article is implemented in a specific educational process at elective classes in geometry and made it possible to increase the efficiency of mastering the studied material by students.
