3 sided geometric figures
The strongest geometric shape is probably the triangular prism.
The only thing that can contain all geometric figures is the set of all geometric figures, which is an infinite set.
A sphere.

Plane figures.
You don't. You can find the area of geometric figures, not of numbers.

No, plane geometric figures are ones like triangles and circles that can fit completely in the plane. A cylinder needs 3, not 3 dimensions and will not fit in the plane.
They are geometric figures.
Transformations. :-)
No. They are universal.
