Titre de la communication :	Classical and computer methods in elementary geometry
Résumé de la communication :
On the base of a personal experience in teacher training in mathematics at the Pedagogical Faculty, University of South Bohemia, Czech Republic a comparison of classical and computer methods in elementary geometry is given. Whereas classical methods show e.g. the beauty of geometry, enable better insight into the geometric situation and better understanding the problem, computer methods (or solving a problem with the help of a computer) make possible to carry out complex computations, dynamic presentation of geometric situations, automatic proving theorems of elementary geometry, automatic derivation and discovery of geometric formulas. On a few examples from geometry of a triangle and quadrangle advantages and disadvantages of the both methods are presented. It is shown that both classical and computer attitude is necessary in teaching geometry to solve geometric problems. The presentation will be accompanied by using dynamic software Cabri and CAS CoCoA.
