A methodology for developing mathematical problem-posing skills, problem-solving skills, and dynamic GeoGebra construction skills has been presented. These skills are an essential component of the professional competence of teachers in mathematics.
The conclusion summarises that the dynamic software GeoGebra and problems for arbelos and Archimedean circles are excellent tools for development skills, mentioned above.
Keywords: GeoGebra, arbelos, Archimedean circles, problem posing, problem solving.
