A truncated prism can be obtained by cutting a prismwith a plane that is parallel to the base or with a plane that is not parallel to the base. However, the result is two prisms when the plane is parallel to the base.
- The lateral faces of a truncated prism are trapezoids.
- By cutting a prism with a plane that is parallel to its bases, we obtain two prisms, not two frustums of a prism.
