The term prism describes the shape of a wedge. It looks like a triangle on the two ends.
Any shape is mathematical.
oval of revolution would be the exact math term for it. Doctor Chuck
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.
2 consecutive circles ============= As a solid geometric figure, a doughnut shape is called a torus.

the mathematical term meaning the line between 2 corners of a 2D or 3D shape. example: a hexagon has nine diagonals
Geometrical symmetry is a mathematical term for a shape that, if torn in half, can be mirrored and restored to the shape again.
Any shape is mathematical.

Volume is the area within a hollow 3 dimensional shape.

A Torus is the mathematical term for a donut shape, that is to say, a circle with a smaller hole within the middle. The plural is toroids.
It is term.
