Geodesic Domes

Definition

Geodesic domes are spherical structures made up of a network of triangles that distribute stress evenly across the surface. This design makes them incredibly strong and efficient, often used in architecture and engineering. The geometric principles behind geodesic domes relate closely to hyperbolic tessellations, where the combination of angles creates unique and efficient forms in both natural and man-made structures.
