Geometric Dissection Puzzle
This page contains a geometric dissection puzzle to play. 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.
