Two-Dimensional Cross Sections Of Three-Dimensional Objects
Gbogbo ọrọ náà
Slice through a solid and the flat shape you reveal is its cross section. Spin a flat shape around an axis and you sweep out a solid. These two ideas link two-dimensional shapes and three-dimensional objects in both directions.
In this lesson you will identify the two-dimensional cross sections of three-dimensional objects, and the solids generated by rotating two-dimensional shapes about an axis.
