The User Interface of GeoGebra Geometry consists of the 
Algebra View, the 
Tools View and the Graphics View. All Views are dynamically connected, which means that modifications in any View are immediately displayed in the other View as well.
Examples:

Examples:
- Drag a point in the Graphics View and watch how its coordinates change in the Algebra View.
Note: Click into the line of a point in the Algebra View to see its coordinates.
- Change something in the Algebra View and watch how it changes in the Graphics View.

The Tools View
Use the Tools View button to open the Tools View providing access to the categories of GeoGebra tools. Select any tool and create new objects in the Graphics View.
Note: The Tools View shows a selection of most important tools. If you want to see more or other tools, select MORE at the end of the Tools View.

Use the Algebra View button to open the Algebra View. Enter algebraic input, commands and functions into the Input Bar using the keyboard. The graphical representation of these objects is displayed in the Graphics View. The algebraic numeric representation of all created objects is shown in the Algebra View as well.

If you don't need the Graphics View you can extend the Algebra View to full screen so you have more space for your input and explorations.
You may also want to only show the Graphics View and to close the other Views. Therefore select the highlighted View from the navigation. You can display other Views again by using the corresponding buttons.

Select 
Settings in the top right corner to open the Settings. 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 Global settings (e.g.: rounding, language), the Graphics View settings (e.g.: grid type, distances on the axes) as well as the Algebra View settings (e.g.: algebra descriptions).
