interactive geometry software for education in schools.Its creator, Markus Hohenwarter, started the project in 2001 at theUniversity of Salzburg and is continuing it atFlorida Atlantic University . GeoGebra is written in Java and thus available for multiple platforms.Dynamic Geometry, Algebra and Calculus
On the one hand, GeoGebra is a dynamic geometry software. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards.On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum.
