# A Challenging Dissection Puzzle

Can you cut the vase in three pieces and assemble them to form a square? Note that the vase is entirely composed of curves.

1. OH GOOD LORD! I looked at the solution and still don’t get it! 🤣 I didn’t get that DNA, apparently! 🙂

2. You challenge my mind Edmark – I didn’t get the puzzle though and was forced to take the easy way out. 🙂

3. From the first reading, I knew that you could not use the image to make the square. These puzzles always seem to force me to at least try. The solution made it clear. Great post.

4. That was a BIG clue you gave, and I didn’t have the patience to think it through. In my defence, I have a cold

5. I can never solve dissection puzzles. Is there any kind of general approach or strategy? Or is it just a matter of insight and intuition?

1. It depends. There are some generalized dissection algorithms for certain types of dissection problems such as lattice-based dissection problems. However, ;you most likely need a computer to run those algorithms.

As for others, it still requires good old trial and error.

6. It’s a clever puzzle. Does the use of the word “vase”, an understood 3D object, help to subvert logic when dealing with simpler 2D figures. It would be fun to find a 3D solution from an actual vase cut and assembled into a cube.

1. Ah, you got me :)

My mind is not good enough to think about 3D dissections. Maybe, it’s possible to find a solution using a computer simulation. I’ll have to ask some friends who know more about this stuff.

7. Very difficult. Consumed many brain cells to think without benefit!😁😁😁
