A polyhedron with the fewest number of faces is a triangular pyramid - it has four faces including the base.
A square pyramid is a polyhedron with a square base and triangular sides that meet at a point at the top. This gives this pyramid five faces.
There are an infinite number of such polyhedra. Starting with a tetrahedron (triangular base), the next up is the quadrilateral pyramid (quadrilateral base), then the pentagonal pyramid, the hexagonal pyramid and so on.

There is no regular polyhedron with 9 vertices There are many other defined polyhedra with 9 vertices, though: elongated square pyramid (cube with a square pyriamd on top) gyroelongated square pyramid triangular cupola triaugmented triangular prism tridiminished icosahedron It's hard to describe the shape of some of these. See the related links below for pictures.
N o
Yes because it has many faces which is the meaning of a polyhedron
A Triangular Pyramid
A three sided pyramid.
Yes and its names is a tetrahedron.
hexahedron ex:cube, triangular dipyramid, triangular deltohedron, pentagonal pyramid
A triangle is not a polyhedron. A triangle is a two-dimensional figure, and a polyhedron is a three-dimensional solid. An example of a triangular-shaped polyhedron is a pyramid.
It is a triangular based pyramid
Yes it is possible,a triangular pyramid or prism
Yes and a triangular based pyramid is a tetrahedron
It can be any type of pyramid.
Yes when in the form of a tetrahedron which is a triangular based pyramid
