A Method for Presenting a Section of Spatial Figures Using

Abstract

This article describes a method for representing the cross section of spatial figures (tetrahedron, prism) in geometry using the Geogebra program. In a geometry lesson, teachers have a great opportunity to use Geogebra elements to show that they can easily find the cross section of shapes in space. Note that, on paper, on a blackboard, sections of pieces in space, students rarely make out. And with Geogebra it's easy to show and visualize. Geogebra can also be used to make the lesson interesting, understandable, and innovative. In addition, students can save all work in electronic format for future use. Analysis of the questionnaire shows that after using the elements of this program in the class, students began to better understand the geometric representation of mathematical concepts. Therefore, the cross-section of figures in space can be made more efficient using the GeoGebra program.
