Explanation:

The complete question is

A triangular prism was sliced perpendicular to its bases and through a vertex. What is the shape of the cross section shown in the figure?

we know that

In a triangular prism, each cross-section parallel to the triangular base is a triangle congruent to the base, and the shape of the cross section of the figure that is perpendicular to the triangular bases and passes through a vertex of the triangular bases is a rectangle
