What constructions with compasses and a ruler, unknown to Thales, did Pythagoras know how to perform? What new polyhedra have become known to him?
Pythagoras was the first to learn to build a regular pentagon with a compass and a ruler. He was also the first to study the regular dodecahedron (Thales knew only the cube, tetrahedron and octahedron). It is not clear whether Pythagoras knew about the existence of a regular icosahedron or whether this figure was first studied by Plato’s disciples 200 years after Pythagoras.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
