To hide the printed fold lines, turn the circle with Dodecahedron - Cut twelve circles with pentagons.įold on each of the three (or four or five) fold lines.Icosahedron - Cut twenty circles with equilateral triangles.Octahedron - Cut eight circles with equilateral triangles.Tetrahedron - Cut four circles with equilateral triangles.When printing from Adobe Reader, you may need to select Auto-Rotate and Center or Choose paper source by PDF page size to ensure the best fit. Related craft: For other geometric solids to make, see the projectĪll of Aunt Annie's project patterns are designed to be printed on standard letter-size paper (8.5"x11" or A4). (cube), and one is based on regular pentagons (dodecahedron). Triangles (tetrahedron, octahedron, and icosahedron), one is based on squares Five solids qualify as regular: three are based on equilateral (or faces) are the same, and the same number of planes meet at each corner (or Property of being regular, or "Platonic". There are many different polyhedra, but five of them have the Three-dimensional objects with only flat (or plane) surfaces are known as This construction technique reinforces theĬoncepts of Platonic solids as the student assembles each solid. Unique calendars-special patterns included!Įach solid is made from a circle, with the shape the solid isīased on drawn inside of the circle. The solids also make nifty boxes, fun decorations and In this project, learn a simple technique based on circles for making allįive Platonic solids-tetrahedron, octahedron, icosahedron, cube, andĭodecahedron.
