Two polyhedra are like two brothers playing or fighting. They rush in a circle or rush forward. After all, polyhedra are related figures.
A polyhedron is obtained by combining two geometric solids - an octahedron and a cube.
The use of two colors - blue for the octahedron and yellow for the cube allows you to see, then, after combining the polyhedra centers—each of the vertices counts belonging to the original polyhedron.
