We have been practising Technical Drawing for some weeks. I know that this part of the subject is difficult, and many of you find it the most boring thing in the world!
As we have drawn lots of polygons, I've thougth it could be a good idea to build 3D polygons. In geometry, they are called polyhedra (polyhedron in singular).
Polyhedra are beautiful 3D geometrical figures that have fascinated philosophers, mathematicians and artists. There are hundreds of polyhedra paper models on this site. And more here.
Our activity will be building a scrapbook icosahedron. You will find detailed instructions here.
- Coloured cardboard
- Geometric compass
- Pencil and rubber
This activity is inspired in Mayalen's "Bola para regalo"
