👉 A semipetaloid is a type of mathematical object commonly used in geometry and algebra. It is a three-dimensional figure that resembles a cylinder, but instead of being flat on one side, it has two sides that are bent inward toward each other, forming a shape similar to a pipe or funnel. In a semipetaloid, the base is curved inward at both ends, while the sides are straight and parallel. This structure allows for many interesting geometric properties, including symmetry and rotational invar
