=====Labelling and formatting objects in Geogebra=====
Once you have created objects, you can label them or format them as per your preferences. The following GIFs show you how to create a label, change the display style of an object you have created and change the labels. The following GIF animations will show how to use these features.

===== Measuring objects in Geogebra=====
You can also measure the objects you have created in Geogebra - the following GIF animations will show you how to use these features.

|Measuring angles
|Measuring segments - by selecting two end points and by selecting the segment
|Measuring area - after describing the given figure as a polygon
|Measuring perimeter of a polygon or circle

#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.
