One of the main goal of this work, based in some axioms which were chosen such that we could obtain an introduction to the study of Spherical Geometry, is to present the spherical trigonometry. We also present a proof of ...

Este trabalho sugere uma sequência de atividades complementares para a geometria. As atividades para a geometria euclidiana plana trabalham com a utilização de régua, compasso, transferidor, telefone celular e também do ...

Os portugueses, diante dos desafios da navegação, proporcionaram grande desenvolvimento e aplicabilidade de técnicas advindas da Geometria Esférica, Astronomia e seus elementos para localização terrestre. Nesse contexto, ...

The present paper serves as a support material for elementary school teachers who teach mathematics, in particular geometry. We recall the calculation of areas of polygonal plane figures followed by mathematical proofs. ...

In this work we present some elements, definitions and theories of Spherical Geometry that will be necessary for its understanding. We found that some results are different when compared to Euclidean geometry, such as the ...

We talk in this work about non-Euclidean geometries, emphasizing in the plane the Poincaré disk model and, in three dimensions, the spherical geometry. In this geometry, we determined some important results, such as the ...
