The User Interface of [i]GeoGebra Geometry [/i]consists of the[i] [img]https://wiki.geogebra.org/uploads/thumb/9/98/AlgebraBlack.svg/24px-AlgebraBlack.svg.png[/img] [i]Algebra View[/i], [/i]the [img]https://wiki.geogebra.org/uploads/thumb/4/49/ToolsBlack.png/24px-ToolsBlack.png[/img] Tools View and the [i]Graphics View.[/i] All [i]Views[/i] are dynamically connected, which means that modifications in any [i]View[/i] are immediately displayed in the other [i]View[/i] as well.[br][br][b]Examples: [/b][br][list][*]Drag a point in the [i]Graphics View[/i] and watch how its coordinates change in the [img]https://wiki.geogebra.org/uploads/thumb/9/98/AlgebraBlack.svg/24px-AlgebraBlack.svg.png[/img] [i]Algebra View[/i][i][/i].[br][b]Note:[/b] Click into the line of a point in the [img]https://wiki.geogebra.org/uploads/thumb/9/98/AlgebraBlack.svg/24px-AlgebraBlack.svg.png[/img] [i]Algebra View[/i][i] [/i]to see its coordinates.[/*][*]Change something in the [img]https://wiki.geogebra.org/uploads/thumb/9/98/AlgebraBlack.svg/24px-AlgebraBlack.svg.png[/img] [i]Algebra View[/i][i][i] [/i][/i]and watch how it changes in the [i]Graphics View.[br][/i][/*][/list]
Use the [img]https://wiki.geogebra.org/uploads/thumb/4/49/ToolsBlack.png/24px-ToolsBlack.png[/img] [i]Tools View [/i]button to open the [i]Tools View [/i]providing access to the categories of [i]GeoGebra[/i] tools. Select any tool and create new objects in the [i]Graphics View[/i]. [br][br][b]Note:[/b] The [img]https://wiki.geogebra.org/uploads/thumb/4/49/ToolsBlack.png/24px-ToolsBlack.png[/img] [i]Tools View [/i]shows a selection of most important tools. If you want to see more or other tools, select [i]MORE[/i] at the end of the [img]https://wiki.geogebra.org/uploads/thumb/4/49/ToolsBlack.png/24px-ToolsBlack.png[/img] [i]Tools View[/i].
Use the [img]https://wiki.geogebra.org/uploads/thumb/9/98/AlgebraBlack.svg/24px-AlgebraBlack.svg.png[/img] [i]Algebra View [/i]button to open the [i]Algebra View. [/i]Enter algebraic input, commands and functions into the [i]Input Bar[/i] using the keyboard. The graphical representation of these objects is displayed in the [i]Graphics View[/i]. The algebraic numeric representation of all created objects is shown in the [img]https://wiki.geogebra.org/uploads/thumb/9/98/AlgebraBlack.svg/24px-AlgebraBlack.svg.png[/img] [i]Algebra View [/i]as well.
If you don't need the [i]Graphics View [/i]you can extend the [img]https://wiki.geogebra.org/uploads/thumb/9/98/AlgebraBlack.svg/24px-AlgebraBlack.svg.png[/img] [i]Algebra View [/i]to full screen so you have more space for your input and explorations.[br]You may also want to only show the [i]Graphics View [/i]and to close the other [i]Views[/i]. Therefore select the highlighted [i]View [/i]from the navigation. You can display other [i]Views [/i]again by using the corresponding buttons.
Open the [img]https://wiki.geogebra.org/uploads/thumb/8/8c/Ic_menu_black.svg/16px-Ic_menu_black.svg.png[/img] [i]Menu[/i] of [i]GeoGebra Geometry[/i] in the top left corner to create [i]New Files[/i], open existing [i]Resources[/i], [i]Save[/i] your work and [i]Share[/i] it with others, as well as to change the [i]Settings[/i], open other [i]GeoGebra Apps[/i] or to get [i]Help[/i] if needed.

Select [img]https://wiki.geogebra.org/uploads/thumb/d/d2/Ic_settings_black.svg/16px-Ic_settings_black.svg.png[/img] [i]Settings [/i]in the top right corner to open the [i]Settings[/i]. Decide if you want to show the axes, a coordinate grid or to change the view on the objects. You can also open further settings to change the [i]Global[/i] settings (e.g.: rounding, language), the [i]Graphics View [/i]settings (e.g.: grid type, distances on the axes) as well as the [i]Algebra View [/i]settings (e.g.: algebra descriptions).
