Question

A pentagonal-based prism is sliced horizontally by a plane parallel to the base. Which figure best represents the shape of a cross-section parallel to the slice?

Since a pentagonal based prism is sliced horizontally by a plane parallel to the base. So the figure must be similar to the base of the prism because it was sliced parallel to base. Since it is a pentagonal based prism, then the cross section is also pentagon in shape
