Vertices, Edges and Faces. A vertex is a corner. An edge is a line segment between faces. A face is a single flat surface. Let us look more closely at each of those: Vertices . A vertex (plural: vertices) is a point where two or more line segments meet. It is a Corner. This tetrahedron has 4 vertices.

A tetrahedron is a shape made out of four triangular faces, and it has a total of six edges. Although each of the four sides of a tetrahedron has three edges, the shape does not have 12 edges, as some of the edges are shared.This figure can also be referred to as a triangular pyramid.

The angle α, is the angle between the two edges connecting the vertex d to the vertices b and c. The angle β, does so for the vertices a and c, while γ, is defined by the position of the vertices a and b. Given the distances between the vertices of a tetrahedron the volume can be computed using the Cayley–Menger determinant:

I need your help! All answers appreciated. How many faces, vertices and especially number of edges does a octahedron have, if you know the answer, can you let me know and explain why. Any diagrams or anything! But anyway, what does a tetrahedron look like? I typed it in Google but it came up with 2 shapes. I'm not sure which is which.

en.wikipedia.org/wiki/Octahedron

In geometry, an octahedron (plural: octahedra) is a polyhedron with eight faces, twelve edges, and six vertices. The term is most commonly used to refer to the regular octahedron, a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex.. A regular octahedron is the dual polyhedron of a cube.It is a rectified tetrahedron. ...
