Question

I have 5 pieces each is a triangle and they are supposed to somehow form a large triangle. Everyone has tried and we can't figure it out. I see lots of solutions online for 7 piece tangrams but nothing for a 5 piece.

Thank you
Zach

I suspect there are 180 solutions to this, and you are studying topology.
