Web(a) Tetrahedron. A tetrahedron is a polyhedron with 4 faces, 6 edges, and 4 vertices, in which all the faces are triangles. (b) Hexahedron. A hexahedron is a polyhedron with six faces. (c) Octagonal Pyramid. An octagonal pyramid has 9 vertices, 9 faces, and 16 edges. (d) Octahedron. An octahedron is a polyhedron with 8 faces, 12 edges, and 6 ... Web30 edges for an icosahedron Euler’s Formula for regular solids F + V - E = 2 For the icosahedron 20 faces + 12 vertices - 30 edges = 2 For regular solids based on triangular faces ONLY such as the icosahedron we have edges are half as many again as the faces. Tetrahedron 4 faces and 6 edges Octahedron 8 faces and 12 edges
Tetrahedron - Math
WebIn geometry, the truncated tetrahedron is an Archimedean solid. It has 4 regular hexagonal faces, 4 equilateral triangle faces, 12 vertices and 18 edges (of two types). It can be constructed by truncating all 4 vertices of … WebAug 27, 2014 · See answer (1) Copy. A tetrahedron is a shape that usually has four faces.

Regular Tetrahedron -- from Wolfram MathWorld
WebThe Tetrahedron has 4 faces, 4 vertices, and 6 edges. The Truncated Tetrahedron has 4 equilateral triangular faces and 4 regular hexagonal faces which totals 8 faces, 12 vertices, and 18 edges. There are 4 more faces on the Truncated Tetrahedron due to the four cuts made. The number of vertices and edges are multiplied by three due to the WebTetrahedron: A tetrahedron has 4 faces, 6 edges, and 4 vertices (corners); and the shape of each face is an equilateral triangle. Cube: A cube has 6 faces, 12 edges, and 8 vertices; and the shape of each face is a square. WebTerms in this set (28) Polyhedron.
