Abstract. Some educational resources for teaching mathematics in the study of midsegments of triangles and trapezoids are described. Variants of dynamic constructions are considered, in support of characterization studies, as well as for the development of the eye-based proportion estimation. Files for 3D printing models when studying midsegments of triangles and trapezoids are presented. The 3D printed models can be used when working with people with visual impairments.
