# Can a polygon be three dimensional?

A polyhedron is a three-dimensional solid bounded by flat polygonal faces, analogous to a polygon in two dimensions. The corresponding shapes in four or higher dimensions are called polytopes.

Also, is a polygon a 2d?

A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A shape with curved sides is not a polygon.

What is the difference between 2d and 3d shapes?

You've just learned the difference between a 2D shape and a 3D shape. The circle is a two-dimensional (2D) shape. It only has two measurements, such as length and height, and is usually called a 'flat' shape.

What is the meaning of 2d and 3d?

2D shapes can be summarized by calling them flat shapes. Any shape that can be laid flat on a piece of paper or any mathematical plane is a 2D shape. As a child, your first drawings probably used basic shapes, such as squares, triangles, and circles.
