University students use technology daily, so that some digital skills are sometimes taken for granted. However, it is necessary for future teachers to use their digital competence in didactic contexts, which is why they must broaden this competence in their academic training and apply it for didactic purposes. The aim of this work is to ensure that future teachers master the techniques related to geometric transformations while improving their digital, mathematical and didactic competence (TPACK Model). For this, the GeoGebra Classic free software application has been used, with the aim of enabling students in training to acquire skills for teaching geometric concepts such as axial symmetry, central symmetry, inversion, rotation, translation and homothetic symmetry. A mixed methodology with a pre-experimental design is used with a sample of 68 participants belonging to the subject of Mathematics and its didactics III of the Degree in Primary Education at the Universidad Rey Juan Carlos enrolled during the 2021/2022 academic year. The notes, the workshops and the data from the expressly designed questionnaire allow for a quantitative and qualitative analysis of the information. The results are very satisfactory since the application of GeoGebra Classic allows the development of strategies that combine competences simultaneously and it is concluded that it facilitates and improves the acquisition of mathematical and digital competence and simplifies some difficulties that emerge in learning.
