Which term refers to a two-dimensional diagram that can be folded into a three-dimensional figure?

• A. Cross-section
• B. Projection
• C. Net
• D. Lattice

Answer: (C)

A two-dimensional diagram that can be folded into a three-dimensional figure is called a net. A net shows all the faces of a 3D shape laid out in the plane with edges that match up when folded. For example, a cube’s net uses six square faces connected in a pattern so you can fold along the edges to form the cube. This distinguishes it from a cross-section (a slice of the object), a projection (a 2D image or shadow of the object), or a lattice (a regular grid-like arrangement). The net is the specific flat pattern that, when folded, becomes the 3D figure.
