GeoGebra is an interactive geometry software for education in schools. GeoGebra is written in Java and thus available for multiple platforms.

Geogebra is a free mathematics software for learning and teaching

  • Interactive graphics, algebra and spreadsheet
  • From elementary school to university level
  • Free learning materials.

Most parts of the GeoGebra program are licensed under GPL and CC-BY-SA, making them free software. However some parts, including the Windows and Mac installers, have a license which forbids commercial use and are therefore not free software. In practice, this means that non-commercial use by teachers and students is always free of charge, while commercial users may need to pay license fees. For details see the GeoGebra license description available at

Please see the associated text box of individual spoken tutorials on the website to decide the versions of Geogebra and OS to which it is applicable.

The Spoken Tutorial Effort for Geogebra is being contributed by Bindu Thirumalai from IT for Change, Bangalore, Madhuri Ganapathi from Spoken Tutorial Project, IIT Bombay and SNDT summer intern Neeta Sawant.
