Geometric
Dissection Puzzle
This page contains a geometric dissection puzzle
that you can try at home.
The shape shown below is a 12-sided polygon, known as a
dodecagon. Print this page, then
use scissors to cut out the dodecagon and also to cut it into
pieces along the lines shown. The
challenge is then to reassemble the pieces to form a hexagon,
which is a 6-sided polygon. This
dissection was discovered by Ernest Irving Freese sometime prior
to 1957. The dissection was
found by overlaying two tessellations, one of dodecagons and
triangles, and the other of hexagons and triangles.
The above
drawing was created by
Robert
Fathauer.
