The session deals with the synthetic construction of specific planar curves which[br]are defined by geometric motions and with the modeling of these constructions in[br]GeoGebra dynamic system. The examples are intended to be used in the undergraduate courses on kinematic geometry but I will show that my approach can be used in mathematical topics which are included in secondary school mathematics too.
