Geometric and Organic Shapes Shapes fit easily into two basic categories: geometric and organic. Geometric shapes are precise and sharply defined. Many of them are easy to recognize, such as circles, squares, and triangles. We often see such shapes in architecture. Also, many manufactured and hand-made products are based on geometric shapes. Nature shows us some geometric shapes and forms too. Honeybees make combs whose cells are in the shape of a hexagon, and an orange resembles the form of a sphere.
