In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The tetrahedron is the simplest of all the ordinary convex polyhedra. The tetrahedron is the three-dimensional case … See more A regular tetrahedron is a tetrahedron in which all four faces are equilateral triangles. It is one of the five regular Platonic solids, which have been known since antiquity. In a regular tetrahedron, all faces are the same size and … See more Volume The volume of a tetrahedron is given by the pyramid volume formula: $${\displaystyle V={\frac {1}{3}}A_{0}\,h\,}$$ where A0 is the area of the base and h is the height from the … See more Numerical analysis In numerical analysis, complicated three-dimensional shapes are commonly broken down into, or approximated by, a polygonal mesh of … See more • Kepler, Johannes (1619).

If all three pairs of opposite edges of a tetrahedron are perpendicular, then it is called an See more There exist tetrahedra having integer-valued edge lengths, face areas and volume. These are called Heronian tetrahedra. One example has one edge of 896, the opposite edge of 990 and the other four edges of 1073; two faces are isosceles triangles with … See more • Boerdijk–Coxeter helix • Möbius configuration • Caltrop See more WebThe Tetrahedron Net. It was artist Albrecht Durer (1471-1528) to first publish the nets of polyhedra. “[Durer] introduces a technique of conveying information about three-dimensional objects on a flat surface via paper-folding which in modern times is called a net.
