In geometry, a tetrahedron (pl.: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertices. The tetrahedron is the simplest of all the ordinary convex polyhedra .

It has four corners and six edges. All four of its faces are equilateral triangles. Every two edges meet on one of those corners forming a sixty-degree angle. A regular tetrahedron is a tetrahedron whose edges are the same length. If the length of an edge is a:

The meaning of TETRAHEDRON is a polyhedron that has four faces. Did you know?

Let us learn more about the tetrahedron shape, a regular tetrahedron, tetrahedron angles, and so on in this article. A tetrahedron is also known as a triangular pyramid whose base is also a triangle. A regular tetrahedron has equilateral triangles, therefore, all …

The regular tetrahedron, often simply called "the" tetrahedron, is the Platonic solid with four polyhedron vertices, six polyhedron edges, and four equivalent equilateral triangular faces, . It is illustrated above together with a wireframe version and a net that can be used for its construction.

Tetrahedrons are polyhedra that have four triangular faces, six edges, and four vertices. All of the faces of a tetrahedron are equilateral triangles. One of its faces is the base, while the other three form the pyramid.

In general, a tetrahedron is a polyhedron with four sides. If all faces are congruent, the tetrahedron is known as an isosceles tetrahedron.

Below is a tetrahedron example. A tetrahedron is a three-dimensional (3D) figure made up of 4 triangular faces. It is also known as a triangular pyramid. If all of the triangles that form the tetrahedron are congruent equilateral triangles, the tetrahedron is referred to as a …

In geometry, a tetrahedron is known as a triangular pyramid. It is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. In simple words, a tetrahedron is a Platonic solid which has a three-dimensional shape having all faces as triangles. (Image will be uploaded soon)
