Find out more about symmetrical 2D shapes. What are 3D shapes? Learn about 3D shapes and their properties. Properties of 3D shapes Learn about faces, edges and vertices.

A 2D shape could have line symmetry or rotation symmetry, or both! 3D shapes are described by their faces, edges and vertices. The faces can be the same shape or different, and a 3D shape could ...

4D materials are first fabricated using 3D printing, then triggered by a stimulus to change their shape. This shape shift can be leveraged for deployable medical ... Some materials also benefit from ...
