No.
a polygon(or polyhedron) is a three dimensional figure that has straight edges. * * * * * A polygon is 2 dimensional, a polyhedron is 3-d.
An arrow can be a polygon. A polygon is any two dimensional plane figure. An arrow can, obviously, be a three dimensional object.
A polygon is a 2-dimensional closed figure that has at least three sides. A pentagon is a 2-dimensional closed figure that has five and only five sides, so it is a kind of polygon.
It could be a pyramid.
polygon
It can be a triangular based pyramid
It is a face of the 3-d figure.
A closed 2-dimensional figure bounded by straight lines. A polygon can have three or more sides.
A polyhedron is a three-dimensional figure formed by flat surfaces that are bounded by polygons joining along their sides (the faces of the polyhedron).A circle is not a polygon, but we can say that a circle is the limit of a regular polygon with n sides. It means that if n becomes larger and larger, the polygon shape approaches to a circle. A circle is a two dimensional figure as a polygon is, but a three dimensional figure whose base(s) is/are a circle cannot be called a polyhedron.
