The above images show you the Geogebra window. After opening Geogebra, you will see the application window as in the second image. The user can define the graphics view in terms of the axes, the grid, scale of the axes, etc. From the View option you can define the number of views you want to see - in this third image, three views are shown - the algebra view, the graphics view and the 3D view. In this handbook, we will primarily discuss the 2D window.

The Geogebra tool bar is very versatile - the construction follows the processes that we would normally follow in paper and pen construction. Some six important categories in the tool bar are discussed below:

#Moving objects:Geogebra allows you to move object constructed freely by dragging the object. You can also select an object and move it by rotating aroung a point.

#Plotting points: There are different ways of plotting points on the Geogebra graphics pad. You can plot a point anywhere on the graphics view - this is a free point. You can also plot on an object or as an intersection of two objects; in both the cases the point is a dependent object.

You can enable toolbar help option which will give you instruction on how to use the selected tool from the toolbar. see the above animation to know to enable this feature.
=====Labelling and formatting objects in Geogebra=====
=====Labelling and formatting objects in Geogebra=====
In geogebra you can label to all the objects but when you are creating sketches geogebra itself will label the object and you can change it manually (see the below animation for the steps). After you create the objects like points, lines, closed For closed Curves and regions you can change the shapes and colours using the Style tab of Menu-options (see the below animations to know the steps).

The above set of images show how to work with some advanced features in the Geogebra tool bar.

#Creating a polygon: The first image shows how to create a polygon by marking the vertices (by plotting points) and completing the polygon.

#Adding a textbox:You can add a text box in the Geogebra file as shown here by clicking on the textbox and clicking anywhere on the graphics view. You will get a box for typing the text you would like to add. Once the text is entered, as shown in the second image, you can right click on the text and after going into Object Properties,format it.

#Angle measurement: The third image shows you how to mark and measure angles. The Geogebra angle tool uses the convention of measuring angles counterclockwise. You can also construct angles with given measure.

#Length measurement: You can also measure sides and lengths as shown in the fourth image. Once you have measured angles and sides, you can drag and move the measurements and lebel to be shown where you would like them to be. This drop down menu also has an option to calculate area.

#Rotation and reflection: As you explore symmetry and congruence, rotating and reflecting an object will be useful to do. In the first of the set of two images, "Rotating and reflecting", the polygon has been rotated by 45 degrees counterclockwise, at a vertex. As in the case of angle measurement, the rotation can be specified to be clockwise or counter clockwise. In the second image the rotated polygon is reflected along a side.

#Inserting image: In the last set of images you see an image being inserted in the Geogebra graphics view. Once you click on insert image, you need to click anywhere on the graphics view to specify the point where the image is to be inserted. Once you click on that, a dialog box will open from where you can choose the image to be inserted.

==== Hide and show objects ====
In Geogebra you can hide any objects and values and you can show it back when you need to display it on the screen. <br>
[[File:Show or hide labels and objects.gif]]
==== Rounding the value ====
To make a rounding of any measurement values, to do that go to options from the menu bar, click on rounding option and selecting decimal places (see the below animation to know the steps) <br>

==== See mobile view of geogebra from your laptop browser ====
To show geogebra mobile app view from your computer, In mozilla firefox web browser > Open "[https://www.geogebra.org/calculator '''https://www.geogebra.org/calculator''']" > right click in next to geogebra title > select "inspect element" > "Responsive design mode".
<gallery mode="packed" heights="250px">
File:1. Geogebra, select inspect elements - In firfox.png|Right click next to geogebra title and select '''inspect element'''
File:2. Responsive design mode.png|Click "'''responsive design mode'''"
</gallery>
This will change online geogebra calculator into Mobile view. once it shows mobile view, close the inspect element window and press "F11" (or fn+F11) function keys to make your screen full view.
