edutech firm Byju's.[3]

History

GeoGebra's creator, Markus Hohenwarter,

University of Linz
.

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 users.

In December 2021, GeoGebra was acquired by edtech conglomerate Byju's for approximately $100 million USD.[3]

On January 25, 2024, lenders began bankruptcy proceedings against GeoGebra's parent company Byju's in an effort to repay its loans.

Chapter 11 bankruptcy in Delaware. Byju's would raise around $200 million in an effort to clear "immediate liabilities" and for other operational costs.[9]

Features

GeoGebra is an interactive mathematics software suite for learning and teaching science, technology, engineering, and mathematics from primary school up to the university level. Constructions can be made with points, vectors, segments, lines, polygons, conic sections, inequalities, implicit polynomials and functions, all of which can be edited dynamically later. Elements can be entered and modified using mouse and touch controls, or through an input bar. GeoGebra can store variables for numbers, vectors and points, calculate derivatives and integrals of functions, and has a full complement of commands like Root or Extremum. Teachers and students can use GeoGebra as an aid in formulating and proving geometric conjectures.

GeoGebra's main features are:

  • Interactive geometry environment
    (2D and 3D)
  • Built-in spreadsheet
  • Built-in computer algebra system (CAS)
  • Built-in statistics and calculus tools
  • hooks
  • Large number of interactive learning and teaching resources at GeoGebra Materials.[10]

GeoGebra Materials platform

The GeoGebra Materials platform[11] is a cloud service that allows users to upload and share GeoGebra applets with others. GeoGebra Materials was originally launched as GeoGebraTube in June 2011, and was renamed in 2016. As of April 2016 the service hosts more than 1 million resources, 400,000+ of which are public. "Materials" include interactive worksheets, simulations, games and e-books created using GeoGebraBook.

GeoGebra Materials can be also exported in several formats, including

PDF and EPS, as well as copied directly to the clipboard. GeoGebra can also generate code for use in LaTeX
files.

Licensing

Before version 4.2, GeoGebra was published under the GNU General Public License (GPL-3.0-or-later).

After version 4.2 the licensing was changed.

proprietary license. User interface image and style files, and documentation and language files are published under the Creative Commons NonCommercial license (CC BY-NC-SA 3.0). Commercial use is subject to a special license and collaboration agreement.[13]

Since parts of GeoGebra not licensed under a GPL compatible license are required to build the program,[14] and since GeoGebra includes GPL licensed libraries,[15] some users,[16][17][18] including a maintainer of one of the libraries used by GeoGebra,[19] consider the license invalid. In response,[20] the International GeoGebra Institute, and GeoGebra's creator, Markus Hohenwarter, have provided a license FAQ.[21]

Community

The International GeoGebra Institute (IGI) is the nonprofit arm of the GeoGebra Group. The institute coordinates research, development, translation and deployment efforts of the GeoGebra system across a global network of user groups at universities and non-profit organizations, as well as provide certification to GeoGebra experts and trainers.
