right prisms could have resulted in that cross section.

right pentagonal prism orright hexagonal prismright hexagonal prism

That is correct. Both a right pentagonal prism and a right hexagonal prism could result in a two-dimensional cross section in the shape of a triangle when cut perpendicular to its base.

A right hexagonal prism is pictured below. Select the type of cross section formed when the figure is cut perpendicular to its base.
