04-UD Geometric Shapes

Let’s start this UNIT 04 with a video called “The Dot and the Line: A Romance in Lower Mathematics“.

It was made in 1965,  by Chuck Jones y Maurice Noble, and it’s bassed on a book . You can find it a bit old-fashioned but it’s interesting because show us some prejudices we can have about geometry
