=====Labelling and formatting objects in Geogebra=====

=====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.

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).

#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.
