Keywords: Non-euclideans geometry | hyperbolic geometry | spheric trigonometry | angle of parallelism

One appears two different forms to obtain the formula of non-euclidian geometry. First assuming the idea of Taurinus, over the formulas hyperbolic geometry are obtained soon from the trigonometry of a sphere with imaginary radio and finally whit rigor of Lobachevsky in their book.
