An ancient pyramid is any of a number of monumental structures built by ancient civilizations in the shape of a pyramid with a rectangular base.
ancient structures were built by man not screws
They are triangular structures
A sphere.
The strongest geometric shape is probably the triangular prism.
I think the strongest 3D shape is a cylinder.
Triangles are considered the most stable shape for structures because they distribute weight and forces evenly. The triangular shape is the strongest geometric shape because it has the smallest possibility of warping or collapsing under stress. That's why many buildings and bridges are designed with triangular supports.

Triangulation is a technique or a method that uses the shape of a triangle on structures that require a lot of strength to serve its purpose, this is why it is popular for building structures from large to small, permanent to temporary. A triangular form is one of the strongest shapes known to man, triangulation of material adds strength by reducing lateral movement.
Colonists built structures.
An inverted U shape is the most common tunnel shape as this is the strongest.
the difference is that natural forces are forces that are created by the enviorment and built structures are not they are built by people #if you bleave in god he will tell you
