Absract. Opportunities are offered for the propedeutics of geometric transformations through two-image difference detection tasks. Ideas related to the compilation of such tasks, methods of using them, opportunities for their promotion through digital technologies are described. The possibility of developing critical thinking, for developing digital competence together with mathematical competence by solving such problems is discussed.
Keywords: geometric transformations; symmetry; critical thinking; GeoGebra; didactic tool; digital competence
