Representing Three-Dimensional Figures with Nets

This lesson covers the representation of three-dimensional figures using nets. It begins with an explanation of dimensions, providing examples of one-dimensional and two-dimensional figures. The core lesson defines a net as a two-dimensional pattern that can be folded into a three-dimensional figure. The video explores different nets for prisms and cylinders, demonstrating how to match nets to their corresponding 3D figures by analyzing their faces and bases.

What is a characteristic of a one-dimensional figure?

• It has length and width.

• It has only length.

• It has width and height.

• It has length, width, and height.

Which of the following best describes a net?

• A two-dimensional pattern that can be folded into a 3D figure.

• A 3D model of a figure.

• A shadow of a 3D figure.

• A drawing of a 3D figure.

How many faces does a prism have if its net has six faces?

• Four

• Five

• Six

• Seven

What is the correct net for a triangular prism with two triangle bases and three rectangle faces?

• Three triangle bases and two rectangle faces

• Two triangle faces and four rectangle bases

• Four triangle faces and one rectangle base

• Two triangle bases and three rectangle faces

Which net is appropriate for a cylinder if the rectangle's length wraps around the circular base?

• A rectangle with equal length and width

• A rectangle with a long length

• A rectangle with a short length

• A rectangle with a short width
