?The use of e-learning and modern technologies is an integral part of teaching descriptive geometry? (Rankowski and Minaruth, 1979). Teachers often create Flash animations, websites and other interactive materials for their students using special tools and software; e. g. Cabri, GeoGebra or Construct 3D (Garciá et al, 2007). All these materials should support development of spatial imagination. However, ?this is the ability most students lack, which results in having problems with understanding simple tasks in descriptive geometry? (Gittler and Judith, 1998). Thus, Monge projection is not a favourite topic for them. This paper continues the article (Ferdiánová and Poruba, 2016), in which paper model of basic tasks in Monge projection, designed as supportive material for teaching geometry, were presented. The aim of the paper is to introduce interactive models for Monge projection, which are very easy to use in e-learning, as well as showing results from practical lesson in which they were used. Models of simple tasks were created in dynamic program GeoGebra, anaglyphs were used for better visualisation of geometric relationships in space. Results from practical lesson were processed with using basic statistical methods such as Wilcoxon test.
