GeoGebra is a dynamic mathematics environment combining geometry, algebra, graphing, calculus and statistical tools. It is designed primarily for education, allowing students and teachers to explore mathematical concepts through interactive visual representations.
The application links geometric constructions with algebraic expressions. Changes to a graph, equation or geometric object are reflected in the corresponding representations, helping users understand relationships that may be less obvious when working with static diagrams.
GeoGebra includes specialised tools for two-dimensional and three-dimensional geometry, function plotting, symbolic calculations and classroom activities. Its broad functionality makes it useful for studying mathematics at different levels.
An important licensing distinction is that GeoGebra’s source code is available under the European Union Public Licence, but the complete GeoGebra product is subject to additional non-commercial restrictions. Its interface materials, documentation and distributed application are therefore not wholly free and open source software.
