What are geometric forms based on? this question is for visual arts edginuity

A geometrical figure is a collection of geometric objects, most often points, lines or planes. Often, the phrase geometric shape is also used for a particular shape or type of geometric object (for example, a point, line, space, a triangle, or a square).

Shapes in three-dimensional space are divided into planar (planar curves and figures) and spatial (spatial curves, surfaces in space and solids). In analytic geometry, linear and quadratic geometric features are divided by the degree of the polynomial that describes them. The basic properties of geometric forms include their measure (length, content, volume, surface or perimeter), dimension, symmetry, continuity or convexity. Geometry also examines relationships between features such as consistency, similarity, and other geometric representations.
