Here is a schematic of the puzzle. So, my solution is translate BC northeast by a small amount transate DE southeast by a small...

bob012345 replied to the thread Geometric Game: Fun With Matches (Safe!).That’s adds to the class of figures in post #15 which I first considered. An interesting question is how many of these types of figures...
