shape
Let an agent handle shape by geometric description, classification, measurement and uses in design and perception.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle shape by geometric description, classification, measurement and uses in design and perception.
The external form, outline or configuration of an object, independent of its position, size and colour in some contexts, described in geometry by properties such as sides, angles and curvature, and recognised by perception.
What it is for: Describing and recognising objects.
It can be classify shapes; describe shape properties; compare shapes with shape measures; use shapes in design and teaching.
Distinguishing features
Geometric form
Invariant under some transformations
Measurable
Perceptually recognised
What it looks like
Outlines and forms of objects, from circles and polygons to complex organic forms.
How it is recognised
Polygons, curves and solids
Symmetry and angles
Being in good shape (fitness) is a figurative sense
