A cross section is the intersection of a plane with a three-dimensional object. It can also be defined as a surface or a shape exposed by making a straight cut through a shape. For example, the horizontal cross section of a cylinder is a circle and its vertical cross section is a rectangle.
After completing this module, you will be able to:
- Define the concept of cross section for three-dimensional objects.
- State the meaning of horizontal and vertical cross sections.
- Identify the cross sections of three-dimensional objects.
