Antipodes sur un tétraèdre régulier. (Antipodes on a regular tetrahedron.)
The goal of this article is to compute antipodes on a regular tetrahedron endowed with its intrinsic metric. The author presents in a first part some elementary results for intrinsic geometry of convex polyhedron. In a second part, he computes antipodes on a regular tetrahedron. In the last part, he gives the diameter and the intrinsic range of a regular tetrahedron.
