**PREFACE : **

This manuscript is intended either as a supplement to a traditional physics course which includes special relativity, or as a textbook for a mathematics topics course in geometry or relativity. The manuscript emphasizes the fact that special relativity is just hyperbolic trigonometry, and includes material on hyperbolic triangle trig, a fascinating and easily accessible mathematics topic in its own right, even without its usefulness in solving problems in relativity..
