Conference publicationsUse of graphic models of spatial figures under solution of geometrical problemsAstrakhan This paper touches upon the problem of usage of graphic models of spatial figures under training geometry. The construction and usage of graphic models of spatial figures in different foreshortenings create didactic foundation for the development of pupils’ space imagination. Under study of planimetry graphic model forms the skills of graphical representation of plane figures as elements of spatial ones. In stereometry graphic model connects the spatial model of figure with its development on plane. |
