A tetrahedron is a polyhedron with four sides (tetra means 4) that are triangles. So one fourth of a tetrahedron is a triangle.
One: a tetrahedron is a single solid.
The ratios are "small to large".
In a molecule of phosphorus fluoride, the phosphorus atom is in the center, and it is surrounded by the three fluoride atoms which are arranged at three of the four points of a tetrahedron. (The fourth point of the tetrahedron contains an electron pair from the phosphorus atom.)
The volume of a tetrahedron is one-sixth of the volume of a parallelepiped because a tetrahedron can be thought of as a pyramid with a triangular base. When a tetrahedron is inscribed within a parallelepiped, it occupies one-sixth of the space defined by the parallelepiped's volume. Since a parallelepiped can be divided into six such tetrahedra, this means the volume of the tetrahedron is 1/6 of the parallelepiped. However, if the parallelepiped is defined by its full height and includes the whole base area, the tetrahedron's volume is one-sixteenth of the total volume when considering the full dimensions of the parallelepiped.
A four faced figure is a tetrahedron. If they are all congruent triangles, they are all equilateral triangles and it is a regular tetrahedron - one of the 5 Platonic Solids.

No.
I am not a tetrahedron!

A tetrahedron.
A pyramid with a triangle as base is considered as a tetrahedron. It is a three dimensional polyhedron with 4 equilateral triangles as its sides. If one would look at the word tetrahedron, it literally means "with four planes".
A silica tetrahedron is composed of four atoms of oxygen bound to a central atom of silicon, with the formula of SiO4.
How many silicon atoms are in a basic silicon-oxygen tetrahedron?i am thinking about 4..
No. The faces of a tetrahedron are equilateral triangles, but none of the faces is parallel to another one of the faces -- they could not be parallel, since by the definition of a tetrahedron, all the faces intersect(!) and parallel planes do not intersect.
