GeoGebra (the name is a portmanteau made from the two words Geometry and Algebra) 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 apps for desktops (Windows, macOS and Linux), tablets (Android, iPad and Windows) and web. 

GeoGebra's creator, Markus Hohenwarter [2] started the project in 2001 as part of his master's thesis at the University of Salzburg. The project is now open-source and multi-lingual, and Hohenwarter continues to lead its development at the University of Linz. 

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

• Scripting hooks

• Large number of interactive learning and teaching resources at GeoGebra Materials.[5]
