This puzzle will test your imagination.
Sheep
If we tie a sheep to one peg it eats out a circle in grass. If we put a rope through a ring on its neck and tie both ends of the rope to two pegs it eats out an ellipse. If we want an oval we tighten one rope between two pegs put a ring with a rope on it and tie the sheep to its other end.
How to tie a sheep so that it eats out a square in grass? We have one sheep ropes pegs and rings.
Hint
Look at the oval how the straight sides were created.
Now all you have to do is apply a similar trick two times...
Answer
Tighten two ropes between corners of a square. Put one ring on each rope and tighten another rope between them. That rope goes through the ring on sheep’s neck.
