GeoGebra

GeoGebra brings together Geometry, Algebra, Calculus, spreadsheets, graphing, statistics and probability applications in a single package.
GeoGebra provides different views for various mathematical objects.

Teachers and students can use GeoGebra to make conjectures and to understand how to prove geometric theorems.
An object in GeoGebra is displayed in different representations (e.g. algebraic and graphical). These representations are linked dynamically.
Equations and coordinates can be entered and modified directly on the screen or through the Input bar. 
GeoGebra Classic’s user interface provides a variety of dialog boxes. It has different accessibility features. The keyboard shortcuts allow us to access many features of  GeoGebra conveniently.

GeoGebra is available for download at www.geogebra.org.
