Regular tetrahedra cannot tessellate space by themselves, although this result seems likely enough that Aristotle claimed it was possible. However, two regular tetrahedra can be combined with an octahedron, giving a rhombohedron that can tile space. However, several irregular tetrahedra are known, of which copies can tile space, for instance the disphenoid tetrahedral honeycomb. The complete list remains an open problem. If one relaxes the requirement that the tetrahedra be all the same shape, one can tile space using only tetrahedra in many different ways.

For example, one can divide an octahedron into four identical tetrahedra and combine them again with two regular ones. As a side-note: The tetrahedron is unique among the uniform polyhedra in possessing no parallel faces. A corollary of the usual law of sines is that in a tetrahedron with vertices O , A , B , C , we have. One may view the two sides of this identity as corresponding to clockwise and counterclockwise orientations of the surface. Putting any of the four vertices in the role of O yields four such identities, but at most three of them are independent: If the "clockwise" sides of three of them are multiplied and the product is inferred to be equal to the product of the "counterclockwise" sides of the same three identities, and then common factors are cancelled from both sides, the result is the fourth identity.

What condition on 12 angles is necessary and sufficient for them to be the 12 angles of some tetrahedron? Since there are four such triangles, there are four such constraints on sums of angles, and the number of degrees of freedom is thereby reduced from 12 to 8.

The four relations given by this sine law further reduce the number of degrees of freedom, from 8 down to not 4 but 5, since the fourth constraint is not independent of the first three. Thus the space of all shapes of tetrahedra is 5-dimensional. The law of cosines for this tetrahedron, [21] which relates the areas of the faces of the tetrahedron to the dihedral angles about a vertex, is given by the following relation:. Then [22]: If A 1 , A 2 , A 3 and A 4 denote the area of each faces, the value of r is given by.

This formula is obtained from dividing the tetrahedron into four tetrahedra whose points are the three points of one of the original faces and the incenter.

Denote the circumradius of a tetrahedron as R. Let a , b , c be the lengths of the three edges that meet at a vertex, and A , B , C the length of the opposite edges. Let V be the volume of the tetrahedron. Then [23] [24]. The centroid of a tetrahedron can be found as intersection of three bisector planes. A bisector plane is defined as the plane centered on, and orthogonal to an edge of the tetrahedron.

With this definition the centroid C of a tetrahedron with vertices x 0 , x 1 , x 2 , x 3 can be formulated as matrix-vector product: The sum of the areas of any three faces is greater than the area of the fourth face. There exist tetrahedra having integer-valued edge lengths, face areas and volume. A tetrahedron can have integer volume and consecutive integers as edges, an example being the one with edges 6, 7, 8, 9, 10, and 11 and volume A regular tetrahedron can be seen as a triangular pyramid.

A regular tetrahedron can be seen as a degenerate polyhedron, a uniform digonal antiprism , where base polygons are reduced digons. A regular tetrahedron can be seen as a degenerate polyhedron, a uniform dual digonal trapezohedron , containing 6 vertices, in two sets of colinear edges.

A truncation process applied to the tetrahedron produces a series of uniform polyhedra. Truncating edges down to points produces the octahedron as a rectified tetrahedron. The process completes as a birectification, reducing the original faces down to points, and producing the self-dual tetrahedron once again. The tetrahedron is topologically related to a series of regular polyhedra and tilings with order-3 vertex figures.

Two tetrahedra in a cube. Compound of five tetrahedra. Compound of ten tetrahedra. An interesting polyhedron can be constructed from five intersecting tetrahedra. This compound of five tetrahedra has been known for hundreds of years. Ashton Satchwell. Kristoffer Thies. Jonathan Rikelme. Justin Small.

    Excuse, that I interrupt you, but, in my opinion, there is other way of the decision of a question.

    I apologise, but, in my opinion, you are mistaken. Write to me in PM, we will talk.
