Number of edges a tetrahedron has
Web11 sep. 2024 · 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 and the only one that has fewer than 5 faces. Contents WebA polyhedron with all triangular faces can be a tetrahedron, an octahedron, or an icosahedron, among others. Let's sketch an octahedron, which has 8 faces, all of which are equilateral triangles. The octahedron has 6 vertices and 12 edges, and each edge is 2 times the length of the triangles' sides.
