A solid figure inclosed or bounded by four triangles.
A basic structural system with 4 triangular faces and 3 triangles around each of its 4 vertices.
A polyhedron with four faces
A four-sided, three dimensional figure used to model a molecule that contains four electron pairs.
1. Four sided polyhedron; all sides are equidimensional and triangular shaped. Minerals shaped as tetrahedrons belong to the isometric system. 2. The building block of all silicates. It is composed of one silicon atom equidimensionally placed around four oxygen atoms. The groups of silicates are classified based on how the tetrahedrons join together.
any polyhedron having four plane faces
a four-sided polygon where all the sides are equilateral triangles
a four-sided solid
a geometric solid figure with four triangular faces
an equilateral pyramid

a solid shape with four triangular sides
a triangularly faceted polyhedron of four faces
a glorified triangle; see sacred geometry.
It is four sided polyhedron. All the sides are equidimensional and triangular shaped. Members belonging to it belongs to the isometric system. Also known as Tetrahedra or Tetrahedrons in plural form.
polyhedron with four faces (tetra=four, hedron=face).
Having four faces. Tetrahedral is one of the crystal forms of diamond.
See regular polyhedron.
The first platonic solid, having four vertices and four sides; attributed to the element of fire, each face symbolizing fire in its different aspects
A Platonic solid consisting of four equilateral triangles.
A tetrahedron (plural: tetrahedra) is a polyhedron composed of four triangular faces, three of which meet at each vertex. A regular tetrahedron is one in which the four triangles are regular, or "equilateral," and is one of the Platonic solids.
