Center of shape's x coordinate is higher than zero (where zero is the middle of the picture).
All examples in this Bongard Problem are small shape outlines.
This is the first Bongard Problem in which absolute positioning is relevant.
Shapes close to the middle would be ambiguous. |

| Non-wiggly outline vs. wiggly outline. |

COMMENTS

"Wiggly" means a high number of small concavities adjacent to one another all around the outline.
All examples in this Bongard Problem are shape outlines.
Shapes with outlines that are only wiggly within partial sections would be ambiguous. Shapes with outlines that have many medium-size concavities would be ambiguous. |
