[i]GeoGebra Geometry [/i]is a dynamic mathematics app connecting geometry and algebra.[br][br]You can access [url=https://www.geogebra.org/geometry]GeoGebra Geometry[/url] online. [br][br][i]GeoGebra Geometry [/i]is also available for [url=https://play.google.com/store/apps/details?id=org.geogebra.android.geometry]Android[/url], [url=https://itunes.apple.com/us/app/geogebra-geometry/id1232591335]iOS[/url], [url=https://download.geogebra.org/package/windows-geometry]Windows[/url] and [url=https://itunes.apple.com/app/geogebra-graphing-calculator/id1294020062]MacOS[/url]. If you are using a different device, you may want to open [url=https://www.geogebra.org/geometry]GeoGebra Web[/url] in your web browser instead.[br][br]In this tutorial, you will learn how use [i]GeoGebra Geometry[/i]. We are still working on including all [i]GeoGebra Geometry[/i] tools and functionalities, which you can use in the Online App, in the Mobile Apps as well, to give you access to the full [i]GeoGebra[/i] power. You can try the examples in this tutorial also on your mobile phone, if there are small differences we will let you know.
