Pentabolo Compatibility


A pentabolo or pentatan is a plane figure formed by joining five equal isosceles right triangles edge to equal edge. There are 30 different pentaboloes, not counting reflections and rotations.

Two pentaboloes are compatible if there is a polyabolo that can be tiled by each. Here I show minimal known compatibility figures for pairs of different pentaboloes.
