Any 2-dimensional shape has a vertex where two sides meet.Any 3-dimensional shape has a vertex where three or more faces meet.
3D shapes are three dimensional, just like 2D shapes are two dimensional.
Polygons are a special type of 2-dimensional shapes.
Two-dimensional shapes are shapes that are flat on the page, such as a square, circle, rectangle, triangle, etc. In contrast, some examples of three-dimensional shapes are cube, sphere, prism, pyramid, etc.
a two dimensional one
A rhombus is a two dimensional figure while the concept of {faces, vertices and edges} is relevant to 3-dimensional shapes.
A polyhedron.
Bases are faces but faces are not necessarily bases.
Nobody shapes can be defined as two-dimensional. All people are three dimensional. Nobody shapes can be defined as two-dimensional. All people are three dimensional.

No. A sphere is a three dimensional shape which has no polygonal faces. Similarly an ellipsoid, a torus, a paraboloid, hyperboloid etc are 3-D shapes with no polygonal faces.
For two dimensional shapes, a vertex (plural vertices) is a point where two sides meet.For 3D shapes, a vertex is a point where three or more faces meet.
They are closed 3-dimensional shapes with polygonal faces.
a cone

A rectangle is a two-dimensional shape, so it doesn't have faces in the way that three dimensional shapes have. A rectangle has four edges and four corners.
A three dimensional shape bounded by plane (flat) faces is a polyhedron.
Any 2-dimensional shape has a vertex where two sides meet.Any 3-dimensional shape has a vertex where three or more faces meet.
