In
elementary geometry, a
polygon is a
plane figure that is bounded by a finite chain of straight
line segments closing in a loop to form a
closed chain or
circuit. These segments are called its
edges or
sides, and the points where two edges meet are the polygon's
vertices (singular: vertex) or
corners. The interior of the polygon is sometimes called its
body. An
n-gon is a polygon with
n sides. A polygon is a 2-dimensional example of the more general
polytope in any number of dimensions.
