GeoGebra is an interactive geometry, algebra, statistics and calculus application, intended for learning and teaching mathematics and science from primary school to university level. GeoGebra is available on multiple platforms with its desktop applications for Windows, macOS and Linux, with its tablet apps for Android, iPad and Windows, and with its web application based on HTML5 technology.
Its creator, Markus Hohenwarter, started the project in 2001 (as part of his master's thesis) at the University of Salzburg, continuing it at Florida Atlantic University (2006–2008), Florida State University (2008–2009), and now at the University of Linz together with the help of open-source developers and translators all over the world.
GeoGebra includes both commercial and not-for-profit entities that work together from the head office in Linz, Austria, to expand the software and cloud services available to its user community.
Interactive geometry, algebra, statistics and calculus
GeoGebra is an interactive mathematics software program for learning and teaching mathematics and science from primary school up to university level. Constructions can be made with points, vectors, segments, lines, polygons, conic sections, inequalities, implicit polynomials and functions. All of them can be changed dynamically afterwards. Elements can be entered and modified directly via mouse and touch, or through the Input Bar. GeoGebra has the ability to use variables for numbers, vectors and points, find derivatives and integrals of functions and has a full complement of commands like Root or Extremum. Teachers and students can use GeoGebra to make conjectures and to understand how to prove geometric theorems.
Its main features are:
- Interactive geometry environment (2D and 3D)
- Built-in spreadsheet
- Built-in Computer algebra system (CAS)
- Built-in statistics and calculus tools
- Allows scripting
- Large number of interactive learning and teaching resources at GeoGebra Materials
GeoGebra Materials Platform
Dynamic GeoGebra applets can be directly uploaded to the GeoGebra Materials platform, the official cloud service and repository of GeoGebra related and interactive learning and teaching resources. GeoGebra Materials was initially launched under the name GeoGebraTube in June 2011 and renamed in 2016. With recent improvement and extended functionality the service now hosts more than 1 million resources (April 2016), 400,000+ of which are shared publicly as searchable materials - such as interactive worksheets, simulations, games, and e-books created using the GeoGebraBook feature.
GeoGebra materials can be also exported in several formats, including as static images or as Animated GIF. SVG vector images can be further edited using third party software, e.g. Inkscape. EMF vector formats can be directly imported in several Office applications. There are also options for exporting to the system clipboard, PNG, PDF, EPS. GeoGebra can also create code that can be used inside LaTeX files through its PSTricks, PGF/TikZ and Asymptote export options.

The International GeoGebra Institute (IGI) is the not-for-profit entity of The GeoGebra Group, coordinating deployment and research efforts across a global network of user groups at universities and non-profit organizations. IGI joins teachers, students, software developers and researchers to support, develop, translate and organise the GeoGebra related tasks and projects. The local user groups support students and teachers in their region. As part of the International GeoGebra Institute network they share free educational materials via the GeoGebra Materials platform, organize workshops, and work on projects related to GeoGebra. The International GeoGebra Institute may certify local GeoGebra users, experts, and trainers according to certain guidelines.
