A pyramid is a polyhedron, one of whose faces is a base. The other faces are triangles having a common vertex.
The regular pyramid is a pyramid that has a regular polygon at its base and the height of the pyramid passes exactly through its center at the base.
The height of the pyramid is a perpendicular section drawn through the top of the pyramid to the plane of its base.
The paper net of the pyramid is a flat geometric figure that completely repeats the surface of the solid and, when bending and gluing, allows you to recreate a geometric solid.
Depending on the number of corners of the base, the correct pyramids determine whether they are:
- triangular or trihedral pyramids;
- quadrangular or tetrahedral pyramids;
To build the pyramid you will need to print a net on a regular sheet of A4 paper. Download shape net.
1. Cut out the net of the pyramid - and bend along the marked lines.
3. Turn the pyramid over and glue the base at No 2.
4. Now we get the shape of a regular pyramid!
For the assembly of polyhedra, we can offer you cut and bent nets.
To do this, you need to use the details of the set Magic Edges No. 14.
In addition, in the very issue you will find information on the structure of polyhedra.
There are five regular polyhedra: a tetrahedron, an octahedron, a cube (also known as a...
