THE CREASE PASSES THROUGH THE TWO POINTS POINT A MOVES TO POINT B INFLATE AT LOCATION SHOWN UNFOLD CHANGE VALLEY CREASE TO MOUNTAIN CREASE CUT WITH SCISSORS ROTATE The Assembly Process Overview There are various methods for folding and assembling modular origami. One can fold all of the pieces before assembling them, or one can install each piece into the model as soon as it is folded. When adding a module, there may be many sites where it can fit into the partially finished model and so an additional level of systematization can be devoted to deciding where to put the module.

Of faces: 10 Shape of faces: equilateral triangle No. of edges: 15 No. of corners: 7 No. of edges or faces meeting at each corner: 5 at north pole or south pole, 4 at the other five corners Polyhedra: Connections with Different Fields Though polyhedra are considered mathematical objects, they find application in many other areas besides math. These areas include art, architecture, astronomy, biology, chemistry and crystallography. Art: The very popular work of M. C. Escher utilizes different polyhedra such as the dodecahedron.

One hint for reading a diagram is to look at the step you are working on, try to do what is shown and then look at the next step to see if what you have folded has been done correctly. If it has been done correctly it will match what is shown in the next step. When reading a step of a diagram you must pay careful attention to all of the information in the step. This includes every mark on the paper. If you are unfamiliar with a symbol, look it up in the Definition of Symbols section. Often several folds are indicated in one diagram step to save space.
