Geometric Origami is a book on the mathematics of paper folding, focusing on the ability to simulate and extend classical straightedge and compass constructions using origami. It was written by Austrian mathematician Robert Geretschläger [ de ] and published by Arbelos Publishing (Shipley, UK) in 2008.
The fold-and-cut theorem states that any shape with straight sides can be cut from a single (idealized) sheet of paper by folding it flat and making a single straight complete cut. [1] Such shapes include polygons, which may be concave, shapes with holes, and collections of such shapes (i.e. the regions need not be connected). The corresponding ...

Paper craft is a collection of crafts using paper or card as the primary artistic medium for the creation of two or three-dimensional objects. Paper and card stock lend themselves to a wide range of techniques and can be folded, curved, bent, cut, glued, molded, stitched, or layered. [1] Papermaking by hand is also a paper craft.
His new American paper would not fit in his English binder so he cut off the ends of the paper and began folding them into different shapes. [3] One of these formed a trihexaflexagon. Stone's colleagues Bryant Tuckerman , Richard Feynman , and John Tukey became interested in the idea and formed the Princeton Flexagon Committee.
The book achieved enough success that the word kirigami was accepted as the Western name for the art of paper cutting. [1] Typically, kirigami starts with a folded base, which is then unfolded; cuts are then opened and flattened to make the finished design. Simple kirigami are usually symmetrical, such as snowflakes, pentagrams, or orchid blossoms.
New technology has also enabled laser-cutting of wooden or acrylic jigsaw puzzles. The advantage is that the puzzle can be custom-cut to any size or shape, with any number or average size of pieces. Many museums have laser-cut acrylic puzzles made of some of their art so visiting children can assemble puzzles of the images on display.
Methods for folding most regular polygons up to and including the regular 19-gon have been developed. [36] A regular n-gon can be constructed by paper folding if and only if n is a product of distinct Pierpont primes, powers of two, and powers of three.
