BP1145 Polygon that can be achieved by folding a square once vs. other polygons.
(edit; present; nest [left/right]; search; history)
COMMENTS

Although it is tempting at first to make a version of this Bongard Problem with the solution "Shape can be achieved by folding a square a finite amount of times vs. other shapes", this alternate Bongard Problem would just amount to having the solution "Convex shape with straight edges vs. concave shape or convex shape with at least one curved edge."
