BP1192

Short, short, long, short, long vs. not.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`All examples in this Problem are paths of short and long line segments which do not self-intersect. This could be a useful world to use in an abstract binary sequence BP.`

BP1199

The only rectangles are the individual regions and the whole vs. there is some other rectangle made of rectangles.

(edit; present; nest [left/right]; search; history)

CROSSREFS

All of the examples fitting left here would fit right in BP1200 except for (1) a single rectangle, (2) two rectangles stacked vertically, or (3) two rectangles side by side horizontally.

All of the examples fitting left in BP1097 (re-styled) would fit right here (besides the two possible arrangements made up of just two rectangles, but those aren't shown there).

See BP1201 for the version with triangles.

BP1200

The whole rectangle can be filled in by successively replacing pairs of adjacent rectangles with one vs. not so.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`Another wording: "can be repeatedly broken along 'fault lines' to yield individual pieces vs not."`

BP1206

Vertical axis of symmetry vs. no vertical axis of symmetry.

(edit; present; nest [left/right]; search; history)

	COMMENTS	`The solution for this Bongard Problem is also a (less specific) solution for BP500, "vertical axis of symmetry vs. no axis of symmetry".`
