Background: Greg Frederickson's book Hinged Dissections: Swinging & Twisting, was published in by Cambridge University thank him for this dissection, originally credited to Dudeney in We have adapted it for use with children.
shown to have a common hinged dissection Hinged Dissections book. Perhaps most intriguingly, Eppstein  showed that ﬁnding a com-mon hinged dissection of any two triangles of equal area is just as hard as the general problem. Hinged dissections are intriguing from the perspec-tives of reconﬁgurable robotics, programmable matter, and nanomanufacturing.
The 5-piece hinged dissection in Figure 15 is from Geoffrey Mott-Smith . The Hinged Dissections book indicates that neither Mott-Smith nor Lindgren, who also created this dissection, identified it as hingeable.
The book then illustrates one of the five possible cases of the hingeable triangle-to-hexagram dissection .

A piano hinge is "a long narrow hinge with a pin running the entire length of its joint.". that the concept of hinged dissections was popularized by Henry Dudeney, who introduced the hinged dissection of a square into a triangle (pictured) in his book The Canterbury Puzzles?" A record of the entry may be seen at Wikipedia:Recent additions//December.(Rated Start-class, Low-importance):.
So, unlike regular hinged dissections, which swing or twist (around single point of hinge), piano-hinged dissections fold along an edge. This book discusses the history, methods, and variations of these dissections and is rich with illustrations that clearly depict the cuts of the dissections and three-dimensional simulations of the dissections in the process of being folded.
Piano-Hinged Dissections: Time to Fold!: : Frederickson, Greg N.: Libros en idiomas extranjerosAuthor: Greg N. Frederickson. Greg Frederickson hates geometric shapes. He hates them so much he has spent the last five years finding new ways to dissect them. We also extend our common dissection result to edge-hinged dissections of solid 3D polyhedra that have a common (unhinged) dissection, as determined.
-SciTech Book News, March Frederickson's first book on Dissections was an encyclopedic survey of all the classical results on geometric dissections with many new extensions. His second book, Hinged Dissections, and the current book extend the ideas into dynamical and three-dimensional versions.
These versions were previously undreamed-of. And then there's the third book about a different kind of hinged dissection that's more of a surface hinged dissection where you've got two--you've got the front and back of this surface and you fold them with like piano hinges with hinges in the plane.
All are very cool books. You should check them out if you want to know more about dissections. Find many great new & used options and get the best deals for Hinged Dissections: Swinging and Twisting by Greg N. Frederickson (Trade Cloth) at the best online prices at. His second book, Hinged Dissection: Swinging & Twisting introduced hinged dissections in which the pieces of a dissection are connected by hinges so that both figures can be obtained by unfolding the dissection in the right way.
Frederickson considered a number of different kinds of hinged joints, including swinging joints between the corners of pieces and twisting joints in which two pieces. According to Frederickson, who published in the most remarkable book on this subject, the idea of hinged dissections originated in early twentieth century with Henry Ernest Dudeney.
Famously, Dudeney also gave a hingeable dissection of the equilateral triangle to a square: . Freese was fascinated by dissections that are hingeable, either completely or partially, and noted positions for hinges in eight of the plates in his manuscript.
This put him ahead of Harry Lindgren, whose book illustrated just three explicit examples of hinged dissections. Inalmost half. Hinged Dissection of Polygons is Hard Over the years, other hinged dissections have been noted , and recently a whole book on the subject has appeared .
In contrast to the situation for unhinged dissections, it is not known whether for any given polygons of equal area, there is a hinged dissec. Hinged dissections: swinging & twisting. [Greg N Frederickson] -- "The illustrations and text will show you how to find hinged dissections for all kinds of polygons, stars, crosses, and curved and even three-dimensional figures.
Greg Frederickson's book, " Hinged Dissections: Swinging and Twisting," delves into a world in which triangles can be transformed into squares, crosses into hexagons, and back again – all with the grace of dancers swinging around a ballroom floor.

famous hinged dissection is Dudeney’s hinged dissection [Dud02]; see Figure 2. This surprising construction inspired many to investigate hinged dissections; see, for example, Frederickson’s book on the topic [Fre02].
However, the fundamental problem of general hinged dissection Cited by: 3. A dissection involves cutting a polygon into pieces in such a way that those pieces form another polygon; for a hinged dissection, the pieces must be attached by hinges. This book discusses the history, methods, and variations of these dissections.
With these ideas, we can prove that hinged dissection of 2 polygons of equal area is possible: Proof of hinged dissection: Start with any valid dissection of the polygons P P P and Q Q Q which have identical pieces.
Hinge the vertices of P P P to form a tree, and do the same for Q Q Q. By claim 6, there is a common subdivision of hinged. We prove that any finite collection of polygons of equal area has a common hinged dissection.
That is, for any such collection of polygons there exists a chain of polygons hinged at vertices that can be folded in the plane continuously without self-intersection to form any polygon in the collection.
This result settles the open problem about the existence of hinged dissections between .Theorem. Let hinged dissection D have two hinge-snugpieces, suchthatthehingedassem-blage on one side of the swing hinge is hinge-re ective.
Then we can modify the two pieces and replace the swing hinge with a twist hinge. 37 Twist Hinged Dissections From Parallelogram Twist 38 Change length of parallelogram: Twist-hingeable Dissection (4 pieces File Size: KB.CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): This is a sequel to the two previous books on dissections by the author  (both reviewed in this newsletter no.
44, September ). In the first book shapes (e.g. a square) were cut to separate (polygonal) pieces and puzzled together again to form another shape (e.g. a triangle).
