Cross Sections
A cross-section is a -dimensional “slice” of a -dimensional figure. Another way to think of it is finding the intersection of a -dimensional plane and a -dimensional figure.
For any given -dimensional figure, the cross-section depends on the orientation of the plane or “slice”. For example, consider a cylinder . Various cross sections might result in a circle or rectangle, as shown below, or any of several other shapes.
