Shapes serve as a visual language for artists and designers to communicate form, structure, and relationships within a composition. Shapes are created when the front and end of a line meet, creating an enclosed space. They are two-dimensional (flat) and should have a length and a width. By adding shadows and highlights to a shape, you can make them look three-dimensional.

Shapes can be inspired by the organic curves of nature or the precision of geometric design to create a specific aesthetic style and to express different feelings and ideas. This conveys important identity, structure, and messaging in graphic design compositions, which enhances their overall impact and effectiveness.
