What you will make:
In this project, learn a simple technique based on circles for making all
five Platonic solids—tetrahedron, octahedron, icosahedron, cube, and
dodecahedron. Each solid is made from a circle, with the shape the solid is
based on drawn inside of the circle. This construction technique reinforces the
concepts of Platonic solids as the student assembles each solid.
Three-dimensional objects with only flat (or plane) surfaces are known as
polyhedra. There are many different polyhedra, but five of them have the
property of being regular, or "Platonic". A solid is regular if all planes
(or faces) are the same, and the same number of planes meet at each corner (or
vertex). Five solids qualify as regular: three are based on equilateral
triangles (tetrahedron, octahedron, and icosahedron), one is based on squares
(cube), and one is based on regular pentagons (dodecahedron).
