HERNANDEZ HECHAVARRIA, Carlos Manuel  y  ACOSTA GARRIDO, Tamara. Didactic use of the GeoGebra in exercises on tangencies of a sphere and a cone: two examples. trf [online]. 2018, vol.14, n.2, pp.226-235. ISSN 2077-2955.

The didactic use of the GeoGebra in exercises of different areas of mathematics and geometry, in particular, is a current issue. This article aims at explaining the teaching of the tangency between bodies, specifically between a sphere and a cone, attending to diagnosed teaching and learning difficulties. It starts with the presentation of two suitable exercises and their corresponding variants to give arguments to prove the convenience of using didactic options suggested by the current versions of the GeoGebra. The examples and arguments shown have contributed to the improvement of the teaching of mathematics and the improvement of teachers of secondary and higher education.
