In basic terms, shape describes a flat, enclosed area of space. Shapes can be constructed with colors and lines, but all shapes are limited to two dimensions – width and length. Curves and other irregular, flowy shapes are known as organic shapes, while angular shapes like squares and triangles are geometric shapes.
The choices can be found elsewhere and as follows:
Ambrogio Lorenzetti
Duccio
Giotto
