cut pyramid
If the pyramid is cut by the surface which is parallel to the base, it is called truncated. In this case the top side formed after cutting has a base form (the same polygon), but in other size - top and bottom bases are congruent.
If the cutting plane is inclined, then after cutting formed sides differ from the base.

There are very much combinations with cut pyramids!
To know what part of a polyhedron it could be, it is necessary to imagine all sides. If they have the common top, it means the pyramid was cut. If there is no common top, it is necessary to look at a shape as a part of a prism.
