Description:
COURSE AIMS AND OBJECTIVES: It is an introductory geometrical course in this study and some kind of a "bridge" course from the secondary school and the so-called university mathematics. The main aim is to systematize and enhance the understanding of elementary (synthetic) geometry. A lot of topics will be presented by means of dynamic geometry software.
