Some Neutral Theorems of Plane Geometry,go a little beyond Euclid in that they use the notion of continuity as it appears in calculus. Results in the last two sections go beyond Euclid in that the ideas in them are more recent, as in the Jordan Curve Theorem or the study of isometries.

Connections with the Lorentz Group of Special Relativity,and show an isomorphism between the direct isometry group of three-dimensional hyperbolic space and the Lorentz group in three space variables and time. We then describe the so-called relativistic velocity space and show that it has the same geometry as the three-dimensional hyperbolic space.
