It's been a looong time since I last visited this forum. (I forgot the username/password for my old account.) But now I'm capable of making my own puzzles (I hope)!

Find the minimum number of straight lines needed to cut a greek cross (example above) into pieces that can be re-assembled to make:

One square

Two congruent squares

Three congruent squares (I don't actually know the answer--or if it's even feasible--but maybe you'll surprise me!)

Four congruent squares

Five congruent squares (It's not quite as obvious as it looks!)

Four congruent greek crosses (I have a solution, but it's probably not optimal)

Five congruent greek crosses (Same as #6)

I'm fairly confident that I have the optimal solutions for 1, 2, 4, and 5. I just threw in the others for an extra challenge.

You can make a cut and re-assemble the resulting pieces before making a subsequent cut.
