The truncated pyramid is a polyhedron formed from a pyramid by cutting off its part by a plane parallel to the base.
The regular truncated pyramid is a truncated pyramid formed from a regular pyramid.
The paper net of the truncated pyramid is a flat geometric figure that completely repeats the body's surface and, when bending and gluing, allows the creation of a geometric solid.
Depending on the number of corners of the base, the truncated pyramids, as well as the regular pyramids, distinguish:
- triangular or trihedral pyramids;
- quadrangular or tetrahedral pyramids;
To create models of truncated pyramids of comparable sizes, you can use the pyramid's property, when a cone can be described near the pyramid.
We chose three cones of various sizes in each of which can be inscribed 3, 4, ... 9-facet truncated right pyramid:
Let's demonstrate what it will look like on an example of a pentagonal truncated pyramid:
Below are the nets for variants of truncated pyramids with a different number of faces:
the base is the regular triangle
the base is the right quadrilateral (square)
the base is the regular pentagon
the base is the regular hexagon
the base is the regular heptagon
the base is the regular octagon
the base is the regular ninth-gon
the base is the regular n-gon
