Take a square, mark the centre, cut out the triangle between the centre and the bottom edge. Glue that onto the right hand side to get an irregular hexagon that I think is vaguely an abstract cow.
Got that?
So the resulting shape, the cow, has a classical two piece dissection where the pieces can be assembled into a square. After all, that's how the cow was constructed.
So ...
Find a *different* two piece classical dissection of the cow where the pieces can be assembled into the square.
Do not give it away !!!
DM me if (or when!) you get a solution.
