Why are three dimensional figure with a curved surface is not a polyhedron?

A polyhedron is defined as a three-dimensional figure composed entirely of flat polygonal faces, which meet at edges and vertices. In contrast, a three-dimensional figure with a curved surface, such as a sphere or cylinder, lacks flat faces and instead has continuous curves. Therefore, the presence of a curved surface disqualifies such figures from being classified as polyhedra.

What can not be a polyhedron?

A polyhedron cannot have curved surfaces; all its faces must be flat, polygonal shapes. Additionally, it cannot have any holes or gaps, as a polyhedron is a solid figure with a continuous surface. Shapes like spheres or cylinders, which have curved surfaces, are also not considered polyhedra.


Is a polygon 3 dimensional?

No. A polygon is a 2-dimensional figure. A polyhedron is 3-dimensional.


Is a triangle a polyhedron?

NO!!! A triangle is a 2-dimensional shape of three sides; archaically a 'trigon'. A polyhedron is a 3-dimensional solid of many sides.
