 Cross cut (Posted on 2006-03-06)
I have a cross in the form of one square with four identical squares surrounding it
```   _
_|_|_
|_|_|_|
|_|```
Cut it into the fewest number of pieces possible such that, when rearranged the pieces form two smaller crosses of identical size.

 Assuming you can "similar" crosses to the original | Comment 3 of 18 |

I've gotten it to 9 pieces.

The trick was to realize that to get two similarly shape crosses of half the size (area), then the linear dimension shrinks to sqrt(2)*original.  Then start cutting on the diagonals.

```    __   | /| __|/\|__
|\   /   |
|/_  \ /\|
|\/|   |/\|```

I'll leave the assembly of the pieces as an exercise for the reader
