One. Vertical through the apex.
Total Eight edges; four vertical and four at bottom.
PyramidGwill help you to calculate the parameters of the golden section pyramid by the desired height or the length of the base, the ratio of which will be the golden section. You can choose the length of the base of the pyramid or the height of the pyramid as the greater value.PyramidG for Cheops calculates the parameters of the pyramid, which base is the golden section of the Cheops pyramid. The calculation is made by the specified values ​​of the height or the length of the base of the pyramid.
You cannot have a 2d pyramid - whether or not it is square based. The 2d cross section will depend on the plane of the cross section.

As many as you want my friend...

The vertical cross section of a right vertical cone is a triangle if that cross section is taken from the vertex. Any other vertical cross section will reveal a hyperbola (with endpoints on the base of the cone). A link can be found below.
If it is lying along its length, and he cross section is, for example, a regular pentagon, then it will have no vertical lines.
A square-based pyramid - line the ones in Egypt - has four edges on its base and four vertical edges rising from the base to the apex - so it has 8 edges.
It depends on the dimensions of the base and the height (slant or vertical) of the pyramid.

It'll help you divide the pyramid into sections that are easy for you to study from
The cross section of a pyramid shrinks from the shape of the base down to a point as you move along its axis from the base to the apex. The cross section of a prism is constant along its axis.
No it is not
