Geometric Dissection Puzzle

5/19/2014

One of the talks I usually give is on geometric dissections, which I begin with the following puzzle from (Lindgren 1964):

I thought it might have been more fun to give the puzzle to the prospective audience one week before I actually presented the solution, so I did that for an upcoming presentation on geometric dissections for students from Raffles Girls' School. I hope they got very frustrated by the puzzle. I also promised to give a hint to the puzzle, but I forgot to post it! Highlight the hint if you want to read it...

Hint

The cut lies on the grid lines.

Fresh poppy pods are the seed pods that are harvested from the poppy flower. Poppies are known for their beautiful flowers, but it’s their seed pods that are of the most value. These pods contain the seeds for the next crop and, when dried, they are frequently used in floral arrangements and other decorative crafts. By using fresh poppy pods, you can take your art to the next level as it gives a natural and pleasant look to your creations.
