Nowadays in the plane geometry with the advancement of technology, the geometric constructions are designed and processed using the 2D dynamic geometry software's (DGSs). In order to use such programs, users should have the necessary information and skill. In this paper, pieces of information some of the known software are given, but more proposed Euklid DynaGeo is presented, in which users can draw and recognize the function graphs more easily. For this aim, some applications are displayed and finally, clearly presented how Euklid DynaGeo serves the users to realize the constructional geometrical drawings.

Maple is used to do numerical computation, plot graphs and do exact symbolic manipulations and word processing. This paper demonstrates how Maple can be used for the simulation of mechanisms. This offers the possibility for students to become familiar with this particular section of mathematical modelling. The mechanism under consideration is a so-called F-mechanisms, i.e., a planar parallel 3-RRR robot with three synchronously driven cranks. It turns out that at this example it is not possible to find the poses of the moving triangle exactly by graphical methods with traditional instruments only. Hence, numerical methods are essential for the analysis of motions which can be performed by an F-mechanism.
