Set Breaker #30: Sheep Shape
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 do we tie a sheep so that it eats out a square in the grass? We have one sheep ropes pegs and rings.
