Abstract:

In the paper some didactic ideas for consciously understanding groups of problems are discussed. The chosen problems are connected with finding out the center of an inscribed and described orb in а polyhedron and a rotational spatial figure. For each group of problems drawings of chosen spatial figures are presented. Using GeoGebra for illustrating the figure plays important role in explaining the possibility to inscribe or describe a given spatial figure. A sample solution of a concrete problem as a logical continuation of a theoretical exposition and its applying is given.
