The contribution describes the use of the freeware GeoGebra for solving geometric-combinatorial problems. We use the freeware not only during online teaching as one of the tools to develop the abilities of first-year students of the Bachelor cycle at the Faculty of Mechanical Engineering of TUL but also during teaching geometry courses determined for the second-year and third-year students of the Bachelor study cycle and the third-year and fourth-year students of the Master study cycle at the Faculty of Science, Humanities and Education to solve geometric tasks and geometric-combinatorial problems. We consider the mentioned areas to be significant from the perspective of future graduates of the Faculty of Mechanical Engineering and the Faculty of Science, Humanities and Education. In this contribution, we present and describe the solutions of selected geometric-combinatorial problems in the GeoGebra environment.
