#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.
