Construir, conjecturar, comprovar i demostrar amb el GeoGebra Authors Pep Bujosa Abstract Construct, propose, verify and prove are four actions we often perform in solving problems of geometry or studying particular properties. GeoGebra allows us to resolve these situations in a very creative way. In this article I review the Van Hiele levels for the construction of geometric thinking and present some examples of activities designed with GeoGebra that can help us on the path toward improved learning. I also review the concept of demonstration and how to adapt it to the context of the classroom, emphasizing the value of the whole process students must follow in order to arrive at the point of a final proof.
