A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...

3D shapes can be made from 2D shapes called nets. Watch the video to learn how 3D shapes, such as a cube, can be created from nets, an arrangement of 2D shapes. Let's talk about nets. More ...

Embryo and organ development is driven in large part by the sculpting of sheets of cells called epithelia. Epithelial sheets have a remarkable repertoire of behaviours — they can narrow and elongate ...
