Polyhedral Surfaces

A polyhedral surface is a 3D shape made up of flat polygonal faces, straight edges, and sharp corners called vertices. Think of everyday objects like a cube or a pyramid: their surfaces consist of flat panels connected along edges. These shapes are typically composed of multiple flat surfaces joined together to form a solid with defined boundaries. Polyhedral surfaces are studied in geometry for understanding shape, structure, and properties of complex forms, and they are used in areas like computer graphics, architecture, and engineering to model and analyze three-dimensional objects.
