What is a two-dimensional diagram that can be folded to form a three-dimensional figure called?

• A. Lattice
• B. Sheet
• C. Plane figure
• D. Net

Answer: (D)

A net is a two-dimensional layout of all the faces of a three-dimensional solid laid out in the plane. Each face is connected to its neighbors along edges so that when you fold along those edges, the faces come together to form the 3D shape. This is different from a lattice, which is just a grid of points or patterns; a sheet is simply a flat piece of material without any implication of folding into a solid; and a plane figure is any flat shape on the plane, not something designed to become a 3D object. For example, a cube can be made from a net of six squares connected in a cross-like arrangement that folds up into a cube.
