In the last activity, you would have tried to create quadrilaterals with two equal sides, all sides equal etc.  You may have found that it is difficult to only visually draw of a given length.  In addition, once you have changed the side, you cannot go back to the earlier construction.

In geogebra, you have a tool called slider which you can use to vary the value of a parameter and by varying it you can study the properties of the figure being constructed.
