. Here is another classic puzzle. On the right I have dissected a square into four identical pieces. And the L-shaped figure has also been dissected into four identical pieces. Can you dissect a square into five identical pieces (of some shape)?

Can you dissect a square into two identical squares? On the left is an attempt. I drew one square (purple) of the correct size, and then tried to arrange the pieces into a second square. This process seems to go on forever. Of course there is a way to perform this dissection. What is the easiest way?

14 (the radius), and the diagonals of a rectangle are
equal. Hm, I wonder why that 7 is backward.

I’m also around to remind you
But in case it’s your way
To give me too much **y,
I can hamper or, even worse, blind you.

Of the numbers I bear
Some in triumph, and some in frustration

Just a mile south of me,
Would that put you in Canada? Yes!

Though no one today seems to know
Every year, millions cry
At the grave where I lie,
In the sunshine, the rain, and the snow.

This position cannot be undone,
If I burn, you may get
Just a little bit wet.
In a zeppelin, I am no fun.
