Shapes on the grid

Place vertices on the dot grid; the property panel prints side lengths, right angles, and parallel marks live. Turn the shape and the panel stays the same. Sort through gates that check one property at a time. The shape is its properties, not its pose.

Choose a mission to open its prediction gate.
