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:

The Geogebra toolbar is very versatile - the construction follows the processes that we would normally follow in paper and pen construction. Some six important categories in the toolbar 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.

#Moving objects:Geogebra allows you to move an 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.

#Drawing lines: The menu for lines and segments also allows multiple constructions - segments,lines, rays and vectors

#Drawing multiple lines: Multiple lines can also be drawn in Geogebra. Parallel lines, perpendicular lines, angle bisectors and perpendicular bisectors can be drawn.

#Drawing circles - You can draw circle, circular arcs and sectors using this tool.
