A POLYGON is a plane figure that is formed by
three or more segments called sides.

• A polygon is CONVEX if no line that contains a
  side of the polygon contains a point in the
  interior of the polygon.

3
A polygon that is not convex is called NONCONVEX
or CONCAVE.

• A DIAGONAL of a polygon is a segment that joins
  two nonconsecutive vertices.

4
A polygon is EQULATERAL if all its sides are
congruent.

• It is EQUIANGULAR if all its interior angles are
  congruent.

• A polygon is REGULAR if it is equilateral and
  equiangular.
