DESCRIPTIVE GEOMETRY AND DYNAMIC GEOMETRY

GeoGebra and Dynamic Geometry Systems (DGS) offer new opportunities for the teaching of geometry and descriptive geometry. These systems make possible to create drawings quickly and flexibly. As regards construction programs in the field of dynamic geometry, as well as traditional constructions and the preparation of static figures, we can shift the fundamentals of the construction at will. The figure being drawn thereby changes consistently, since the program views the figure as a dynamic whole. Moreover, these systems can store the construction steps and execute them after modification of the input data. So by means of movement it can be observed how figures are constructed upon each other, as well as the construction process itself. We may assert on the basis of these results that use of interactive worksheets provided by DGS increases success, helps to create a proper conceptual structure and it is also a useful help to improve the students outlook in geometry.
