Cross-sections of solids

What you'll learn

1. Define a cross-section as the 2D shape formed when a plane cuts through a 3D solid
2. Identify the cross-section produced by horizontal, vertical, and diagonal cuts through rectangular prisms, cylinders, cones, pyramids, and spheres
3. Recognize how changing the angle or position of the cutting plane changes the resulting cross-section
4. Identify which 3D solid results from rotating a given 2D shape around a specified axis
5. Solve ACT-style problems that ask for the shape of a cross-section or the solid generated by a rotation
