Platonic Solids in a park in Steinfurt, Germany We would like to talk about 5 platonic solids. The definition of a platonic solid is a shape where you’ve got sort of different sides to the shape, but all of the sides are the same shape. That shape is a regular kind of polygon - so like the square where all the sides are the same length and the angles are all the same and every corner looks the same. This is called a tetrahedron . It’s faces are regular polygons, regular triangles. It has the same number of triangles meeting at each corner. Tetrahedron is like a pyramid, but unlike the pyramid - it has a triangular base, not a square base. It contains of 4 faces, 4 vertices and 6 edges . To jest czworościan foremny (tetraedr). Składa się z 4 trójkątów równobocznych i ma taką samą liczbę ścian przystających do każdego z wierzchołków. Ma 4 wierzchołki i 6 krawędzi . This is the octahedron . It has eight (the preffix ’oct’ m...
