What is GeoGebra

GeoGebra is dynamic mathematics software that joins geometry, algebra and calculus. It is developed for learning and teaching mathematics in schools by Markus Hohenwarter and an international team of programmers. This manual covers the current version (4.0). GeoGebra is backward compatible with all previous versions, despite small differences.

Install GeoGebra

The Installation Guide will help you with installation and system integration of GeoGebra in various operating systems.

Get to grips with GeoGebra's user interface

The main window is divided to views. By default Algebra View is displayed on the left side and Graphics View on the right. Above these views there is a Menubar and Toolbar, underneath Navigation Bar can be placed. Many features of GeoGebra can be accessed via Keyboard Shortcuts. GeoGebra also includes accessibility features such as Virtual Keyboard.

• create HTML Dynamic Worksheet via Java applets or HTML5
• print the construction, possibly with Construction Protocol
• export as image (PNG, SVG, PDF, EPS, EMF) or to LaTeX and Asymptote.
• get the applet in a self-contained string suitable for Google Sites, Mediawiki or Blogger – no file upload needed
• upload the construction to GeoGebra
