GeoGebra, Non-Euclidean Geometries, Spherical TrigonometryAbstract
In this work, we present some results on spherical trigonometry and use them to solve navigation problems involving distances between points on the globe. In order to facilitate visualization and location, we developed an applet in GeoGebra 3D that simulates planet Earth, displays points on the Earth's surface by providing latitude and longitude and calculating the distance between them. We conclude that GeoGebra is an effective tool for studying spherical geometry, and can be used both in undergraduate courses and in basic education.
