Understanding Nets, Pyramids, and Prisms

This video tutorial introduces the concept of nets in geometry, explaining how two-dimensional shapes can be folded to form three-dimensional shapes. It covers definitions and examples of nets, focusing on the differences between pyramids and prisms. The video provides detailed explanations of these shapes, including their properties and how to identify nets that form them. Viewers are encouraged to practice identifying nets and determining whether they form pyramids or prisms.

What is a net in geometry?

• A pattern that cannot be folded.

• A two-dimensional shape that can be folded to form a three-dimensional shape.

• A three-dimensional shape that can be folded to form a two-dimensional shape.

• A shape that is always flat.
