Oh dear! Oh well. The spheres are disappointed and one is angry. 3D shapes have faces (sides), edges and vertices (corners). Faces - A face is a flat or curved surface on a 3D shape. For example a ...

While they may have sharp edges there are no corners, or points where two or more line segments meet. Shapes capable of tiling a 2D space need a minimum of two corners, but in 3D the rules are ...

However, many tilings in nature are characterized by shapes with curved edges, non-flat faces, and few ... and minimize the amount of “corners” present. In 3D, a soft cell shape can have ...
