Geometric form

Geometric forms are forms that can be constructed using geometry, such as squares, rectangles, circles, cones, cubes, and so on. Geometric forms are commonly found in architecture, structural and civil engineering.
This is as opposed to 'organic' forms which are generally complex, irregular or asymmetrical, and cannot easily be constructed using geometry. naturally-occurring forms are often considered to be 'organic'.

Two-dimensional geometric forms are often defined by a chain of points or vertices are connected by lines. These are referred to as polygons (triangles, squares, pentagons, hexagons, and so on). They can also be bounded by curves (circles, ellipses, and so on).
Three-dimensional geometric forms are often defined by two-dimensional faces enclosed by lines that connect a set of vertices. These are referred to as polyhedrons (cubes, pyramids, cones, and so on). They can also be bounded by curved surfaces (ellipsoids, spheres, and so on).
