Tetrahedron - Wikipedia 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 [1]
Meaning, Properties, Formulas | Tetrahedron Shape - Cuemath 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 its interior angles measure 60°
Tetrahedron - Math. net 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 regular tetrahedron
Spinning Tetrahedron - Math is Fun The molecule methane (CH 4) has a tetrahedral shape, with 1 carbon atom at the center and 4 hydrogen atoms at the vertices: A 3D shape with 4 flat faces Notice these interesting things: It has 4 faces It has 6 edges It has 4 vertices (corner points)
Tetrahedron -- from Wolfram MathWorld In general, a tetrahedron is a polyhedron with four sides If all faces are congruent, the tetrahedron is known as an isosceles tetrahedron
