No. A polygon is a plane area bounded by straight lines. The key term in this context is "plane". It is, therefore, 2 -dimensional shape. A solid, which is bounded by faces that are polygons, is called a polyhedron (plural = polyhedra).
Starting with the definition of polygon makes much easier to understand why triangle is a polygon.Definition: A polygon is a closed figure bounded by sides.Definition of triangle: Triangle is a closed figure bounded by three sides.Since triangle is also a closed figure bounded by sides therefore, triangle is a polygon.
Polygon: A closed shape bounded by straight lines.
A cube.
A regular prism.

A polyhedron is a solid object bounded by polygons. Polygons are plane shapes [bounded by straight lines]. The curved surface of a cone is not a polygon and so the cone is not bounded by polygons and therefore, a cone is not a polyhedron.
A polygon is a closed figure bounded by sides. A triangle is a closed figure bounded by three sides. Therefore, according to the definition of polygon triangle is a polygon.
polygon is a closed figure which is bounded by line segments.

A polygon is a closed plane shape which is bounded by straight lines. A quadrangle is a polygon with 4 sides.
A cube.
A regular prism.
There is no such solid.
