Question

how would the vertical cross section of this triangular prism look?

Explanation:

Step1: Analyze the shape of the triangular prism

A triangular prism has two triangular bases and three rectangular lateral faces.

Step2: Consider the vertical cross - section

When taking a vertical cross - section of a triangular prism (assuming the vertical direction is perpendicular to the bases), the cross - section will be a rectangle. This is because the vertical cut will pass through two of the parallel lateral edges (which are part of the rectangular faces) and the distance between the two triangular bases.

Answer:

The vertical cross - section of the triangular prism is a rectangle.
