Ideas for Improving Mathematics Teaching by Using the GeoGebra Mathematical Software

Abstract

This paper deals with some uses of the GeoGebra mathematical software with the aim to improve and modernize mathematics teaching. It proposes some ideas for systemizing activities and problems related to solving a triangle. The problems are presented in two groups – basic and additional, each of which has subgroups. The purpose of the drawings is to illustrate the respective problem, to facilitate its solution, and to demonstrate the main requirement to learn mathematical concepts – to vary the insignificant properties of a concept to make the significant ones stand out.
