The goal was to show some properties of polygons and to prove the Pitagora’s theorem by using the geometry of the transformations and through the utilisation of a dynamic Geometry software.</p>}, number={2}, journal={EDiMaST: Experiences of Teaching with Mathematics, Sciences and Technology}, author={Marincola, Rosa}, year={2018}, month={Mar.}, pages={14} }
