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

The geometic term for the shape of a 50 Pence coin is a "Heptagon".
Ah, what a delightful shape to paint! The mathematical name for a 3D egg shape is called an "ellipsoid." Just like how we blend colors on our canvas to create depth and dimension, mathematicians use equations to describe the curves and proportions of different shapes like the ellipsoid. Embrace the unique beauty of each shape you encounter, my friend, and let your creativity flow like a gentle stream.
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.
There is no specific name. There are spheres, ellipsoids, paraboloids, etc. Then there are 3-d cycloids,
Geometrical symmetry is a mathematical term for a shape that, if torn in half, can be mirrored and restored to the shape again.
It depends on the 3d shape.
