Learning objectives

The student will identify the shapes of two-dimensional cross-sections of prisms, cylinders, pyramids, cones, and spheres.

The student will compare and contrast vertical, horizontal, and angled cross-sections of three-dimensional figures.

Real world application

When engineers are designing a structure to be built, they have to make sure that all of the pieces fit together correctly. In order to do this, they must consider the two-dimensional cross-sections of three-dimensional objects and arrange the objects so that their cross-sections fit together.
