A pyramid is a polyhedron, one of whose faces is a base. The other faces are triangles having a common vertex.
The pyramid height 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 solid's surface 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;
We open the veil of the secrets - how our products are made. And let's do it on the example of...
