No shape is mathematical really unless it has been created by a mathematical formula, but is certainly a geometric shape. But anything which is a 2D or 3D shape is geometric. My improvement: A catenary curve from a mathematical equation such as cosh x, is a mathematical and natural shape. Maby each other arch can be approximated by a mathematical formula.
The term prism describes the shape of a wedge. It looks like a triangle on the two ends.
There is no specific name. There are spheres, ellipsoids, paraboloids, etc. Then there are 3-d cycloids,
Any shape is mathematical.
the mathematical term meaning the line between 2 corners of a 2D or 3D shape. example: a hexagon has nine diagonals

Oh, dude, you mean like an oval-shaped egg but in 3D? That would be an "ellipsoid." It's like the fancy mathematical term for a squished egg shape. So, next time you're trying to impress your friends with your knowledge of 3D egg shapes, just drop the word "ellipsoid" and watch their minds be blown.

The geometic term for the shape of a 50 Pence coin is a "Heptagon".
2 consecutive circles ============= As a solid geometric figure, a doughnut shape is called a torus.
Yes but the correct term is octohedron
The term prism describes the shape of a wedge. It looks like a triangle on the two ends.
An 18 sided shape is called a octadecagon. This refers to both 2 dimensional and 3 dimensional shapes in a mathematical sense.
Geometrical symmetry is a mathematical term for a shape that, if torn in half, can be mirrored and restored to the shape again.
There is no specific name. There are spheres, ellipsoids, paraboloids, etc. Then there are 3-d cycloids,
It depends on the 3d shape.
