Example 2 Identifying a Three-dimensional Figure from a Net 10.1.1 Solid Geometry (continued)
The three-dimensional figure that can be made from a net is described in this example. The net can be folded into the three-dimensional shape of a cylinder. The bases are formed by the two circular faces of the net and are joined by the curved surface of the net’s rectangle.
The three-dimensional figure that can be made from a net is described in this example. The net can be folded into the three-dimensional shape of a pentagonal pyramid. The base of the pyramid is the pentagonal shape of the net. The faces of the pyramid are the five triangular shapes of the net that fold up to join at the vertex.
Example 3 Describing Cross Sections of Three-Dimensional Figures
A cross section of a rectangular prism is described in this example. The cross section of this rectangular prism is a square. Note that this is not the only cross section that could be made of this figure. Other cross sections might not form a square.
