The Tetrahedron

The Tetrahedron is a regular three-sided Pyramid. Its surface consists of four equilateral triangles and is therefore one of the five Platonic solids.

The following elements of a tetrahedron are calculated if one of them is given:

Example:

Gegeben:  Umkugelradius  ru = 1

Ergebnisse:
                    Kante a = 1,6329932
             Flächenhöhe h1 = 1,4142136
                Raumhöhe h2 = 1,3333333
           Umkugelradius ru = 1
           Inkugelradius ri = 0,33333333
                  Volumen V = 0,51320024
               Oberfläche O = 4,6188022
