It's hard to answer that straightforwardly=)

what's the big deal?

Easy.

 
Did the condition say that the dots were placed symmetrically? :)
 
Candid >>:
А что, в условии было что точки симметрично ставились? :)

One can prove the contrary with individual cases. So the irony is misplaced. There was no contrary condition either.

 

TheXpert, all that's left to prove is that it's all squares. It's sort of almost obvious though.

OK, then let's assume that the 4 remaining points don't form a square.

There were no other conditions. Probably solving the problem involves analyzing different cases, including "degenerate" ones, i.e. having many solutions. The source where I found the problem is trustworthy.

 
TheXpert >>:


Легко.


Yep

I was in a hurry (

 
I smell a compass.)
 
TheXpert >>:

От противного можно доказывать частными случаями. Так что ирония неуместна. Обратного условия тоже не было.

I had hoped that what was said with a kind smile would be taken more easily. Well, if I was wrong, I'm sorry.

And what exactly did you refute in this case?
