• Resumen

  • The concep of a semi-regular polygon does not arise as subordinate to the concept of regular polygon, but rather it is induced by that of a semi-regular polyhedron. Therefore, a semi-regular polygon is one in which all its vertices are indistinguishable. Thus, all its angles are equal, and at every vertex, two sides of lengths "a" and "b" meet.
