Divide and Conquer

The solution:
When I reached the last part of the riddle (i.e. dividing the square to five parts) I thought it was kind of stupid. Zohar claimed that many people find this part as the hardest, as they expect it to be so, and so they don’t see the obvious.
This seemed to me like a good opportunity to test the new poll system. So please participate:

Number 4 took me two weeks (actually, I did the first 3 in five seconds, then got stuck on the 4th one, and only now looked at the solution).
Actually, the reason is I thought the “allowed operations” are limited – in the first three I only did stuff I can actually do quite percisely without resorting to any measurements – only connecting points and continuing lines which already appear in the picture. (I had a different solution for number 3 which follows these rules). Of course if you’re allowed to measure the distance and divide by 5, number 4 is super-easy, but I didn’t think I was allowed. (Of course, I had no reason to think I wasn’t allowed to do so, and it’s pretty silly to make up rules when solving a riddle
)
