Definition of a
Pyramid*:
A pyramid is a polyhedron with one face
(known as the "base") a polygon and all the other faces triangles meeting at a
common polygon vertex (known as the "apex"). A right pyramid is a pyramid for
which the line joining the centroid of the base and the apex is perpendicular to
the base. A regular pyramid is a right pyramid whose base is a regular polygon.
An n-gonal regular pyramid (denoted Yn) having equilateral triangles as sides is
possible only for n=3, 4, 5. These correspond to the tetrahedron, square
pyramid, and pentagonal pyramid, respectively.
