The above image shows you the Geogebra window. After opening Geogebra, you will see the application window as above. The user can define the graphics view in terms of the axes, the grid, scale of the axes, etc. The Move button - which allows objects to be moved is highlighted in blue.

===Typing text in a textbox===

The textbox is used to write descriptive text in a Geogebra file. The first image shows you the option in the tool bar which will be used to insert a text box. After selecting the text box option, you can click anywhere on the graphics pad to insert the text box. The next two images show how symbols and prior defined objects can be inserted. For example, in the third image, the "α" object is a prior defined object - the angle measure. This feature allows the text box to dynamically capture the changes in the Geogebra file.

===Defining a slider===
One of the powerful features of Geogebra is the dynamic feature. You can vary parameters of the shape that you want to animate and see how properties change.

#When you define a slider, you can also set up animation on - this keeps changing the value of the parameter and keeps changing the sketch

===Defining a checkbox===
A checkbox is a useful way to control the sequence of display of objects in a Geogebra file and hence can be an useful way to structure a lesson.
