Difference Between a Polygon and a Polyhedron


Question: What is the difference between a polygon and a polyhedron? 

Polygon defined as a plane figure with at least 3 sides and 3 angles. In Polyhedron, poly means many, and hedron refers to surface. The polyhedron is defined by the number of faces it has.

Answer: A polygon can be defined as a flat or plane figure, that is a 2-dimensional closed shape with straight sides. A polyhedron is defined as a solid figure, that is is a 3-dimensional solid made by joining together polygons.

Polygon is a 2-dimensional shape and polyhedron is a 3-dimensional shape.

Explanation:

Polygon is composed of a finite sequence of straight lines known as edges or sides and polyhedron is composed of flat faces and straight edges.

Examples of polygon - triangle, rectangle, pentagon.

Examples of polyhedron - triangular prism, rectangular prism.

Therefore, a polygon can be defined as a flat or plane figure, that is a 2-dimensional closed shape with straight sides. A polyhedron is defined as a solid figure, that is is a 3-dimensional solid made by joining together polygons.
