- Abstract:
-
A hinged dissection of a set of polygons S is a collection of polygonal
pieces hinged together at vertices that can be folded into any member of
S. We present a hinged dissection of all edge-to-edge gluings of
n congruent copies of a polygon P that join corresponding edges
of P. This construction uses k n pieces, where
k is the number of vertices of P. When P is a regular
polygon, we show how to reduce the number of pieces to
⌈k / 2⌉ (n − 1). In
particular, we consider polyominoes (made up of unit squares), polyiamonds
(made up of equilateral triangles), and polyhexes (made up of regular
hexagons). We also give a hinged dissection of all polyabolos (made up of
right isosceles triangles), which do not fall under the general result
mentioned above. Finally, we show that if P can be hinged into
Q, then any edge-to-edge gluing of n congruent copies of P
can be hinged into any edge-to-edge gluing of n congruent copies of
Q.
