3. Cut a 3×3 square without the central cell into 5 pieces that can be assembled into a square?
#
This one wants a proof. Work it on paper, read the official solution, then mark
yourself honestly — the ladder only means something if the record is true.
Official solution
# Solution:
The solution is shown in the figure. On the left fragment - the cutting. On the right - the assembly scheme of the new square.
## Instructions for checking:
!
If the solution is done on a grid, no justification for the correctness of the cutting and assembly is required.
If the scheme is not on a grid, errors are very likely. Be attentive!
