Question

which two - dimensional shape could be created by a plane slicing vertically through this hexagonal pyramid? a octagon b square c hexagon d pentagon

Explanation:

Step1: Visualize vertical slice

A vertical slice through a hexagonal pyramid will pass through the apex and two opposite vertices of the hexagonal base.

Step2: Count sides of cross - section

The cross - section will have 5 sides. It has two edges from the triangular faces of the pyramid and three edges from the base (since it cuts through two opposite vertices of the hexagon).

Answer:

D. pentagon
