symmetry
For the first video on the subject of symmetry, a grasshopper definition meant to explain rotational symmetry with the pentagonal dodecahedron. symmetry
my ph.d. thesis on polyhedra
My doctoral thesis “Aplicações Didácticas sobre Poliedros para o Ensino da Geometria” (Didactic Applications on Polyhedra for the Teaching of Geometry) is available online in this link. Some of its didactic applications will be included in this website (the ones available are found in this webpage , this one and also this). I will publish […]
convex semiregular polyhedra
The webpage concerning the convex semiregular polyhedra includes tutorials meant to show how to model: the truncated tetrahedron from the regular tetrahedron; the truncated cube from the cube; the truncated octahedron from the regular octahedron; the truncated octahedron from the cube.
