Folding geometric shapes helps visualize which concept?

• A. Area of 3D shapes
• B. Angles in 2D shapes
• C. Nets of 3D shapes
• D. Volume measurement

Answer: (C)

Folding geometric shapes helps you see nets of 3D shapes. A net is a flat plan that shows all the faces of a 3D figure laid out in one piece. By folding along the edges, you can predict how those faces come together to form the solid, notice which faces are adjacent, and understand how the 2D pattern becomes a 3D object. For example, a net made of six squares can be folded into a cube, illustrating exactly how each square becomes a face and how the edges meet. This makes the connection between flat patterns and real solids clear, rather than focusing on calculating area, volume, or analyzing angles in a 2D figure.
