Geometric abstraction is a form of abstract art based on the use of geometric forms sometimes, though not always, placed in non-illusionistic space and combined into non-objective compositions.
It is a curved line that forms part of the circumference of a circle.

The radius of the sphere of which a lens surface or curved mirror forms a part is called the radius of curvature.
The meniscus is the name for the way that water forms a concave curve at it's surface. This is because of the cohesive and capillary properties of water.
Egyptians excelled in many geometric forms, including squares, triangles (pyramids), and spheres.
I disagree with the post from earlier: No, only geometric. Organic means natural, not artificially improved or created. if it brought you to this when u were asking about forms not shapes the answer is not only geometric -- At least as far as art goes the following is true: Shapes can be organic, geometric or irregular. At least from the stand point of an artist.
The curved surface at the top of a liquid is called the meniscus. It forms due to surface tension, causing the liquid to either curve upwards (concave meniscus) or downwards (convex meniscus) at the edges where it meets the container.
Geometric means (1) "relating to geometry" or (2) "having simple geometric forms such as circles and squares in design or decoration."
Forms can be both geometric and organic, depending on their characteristics. Geometric forms are characterized by precise, mathematical shapes like circles or squares, while organic forms are irregular, flowing, and often found in nature, like the shape of a leaf or a cloud. Some forms may exhibit elements of both geometric and organic qualities.
