Pyramids cross-sections

Pyramids cross-sections

Issue 32 "Magic edges"

In this issue, parts for assembling 3 pyramids with 7 sections deposited on them. Since the tetrahedron was chosen as the shape of the pyramid, all the presented sections can be considered as sections of the tetrahedron.

We suggest that you collect three pyramids with the cross sections in the form of polygons plotted on them: triangle, square, rectangle, quadrangle, trapezoid.

Each of the 3 pyramids can be useful to you as a visual aid for solving mathematical problems.

green pyr 1

The green pyramid has two cross sections - in the shape of a rectangle and a square

 

white pyr 1

The white pyramid has two cross sections - in the form of an isosceles triangle and a trapezoid

 

red pyr 1

The red pyramid has three cross sections - in a quadrangle, an isosceles triangle and an equilateral triangle
