A Geometria esférica e o globo terrestre : interdisciplinaridade e possibilidades de ensino

Abstract

This work is a descriptive study made from bibliographical research and aims to explore the relation between the main concepts of spherical geometry and the Earth's globe, contributing to the study and teachings of mathematics in an interdisciplinary manner. For this, we present a brief discussion about the beginning of non-Euclidean geometries with an emphasis on spherical geometry. We brought the main concepts of this geometry and its definitions as well as the main characteristics of the Earth's globe. We approached the relation between these concepts in which we used "GeoGebra" and "Google Earth" as technological support and, lastly, we suggest an activity proposal, in which we calculate the distance between two points on the Earth's surface.
