What would be the cross section of a hexagonal pyramid from a vertical slice?

A cross section is the shape you see when you make one slice through a solid. A solid can have many different cross sections depending on where you make the slice. Consider the following hexagonal pyramid. Cross sections perpendicular to the base and through the vertex will be triangles.

The cross section of a hexagonal pyramid from a vertical slice would be a triangle. If you slice the hexagonal pyramid vertically and straight in the middle, you would see a triangle.
