1. A polygon is a plane figure with three or more than three segments.
POLYGONS
A polygon is a plane figure with three or more than three segments.

2. THEY ARE OF 2 TYPES-
REGULAR POLYGONS
IRREGULAR POLYGONS

3. REGULAR POLYGON
regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length). 

4. IRREGULAR POLYGONS
Any polygon that is not a regular polygon. A polygon whose sides are not all the same length or whose interior angles do not all have the same measure .

5. They can also be divided into
CONVEX POLYGON
CONCAVE POLYGON

6. CONVEX POLYGON
A convex polygon is a simple polygon whose interior is a convex set.[1] The following properties of a simple polygon are all equivalent to convexity:
Every internal angle is less than or equal to 180 degrees.
Every line segment between two vertices remains inside or on the boundary of the polygon.

7. CONCAVE POLYGON
A simple polygon that is not convex is called concave,[2] non-convex[3] or reentrant.[4] A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.[5]

8. POLYHEDRON
polyhedron is a solid with flat faces (from Greek poly- meaning "many" and -edron meaning "face").
Each face is a polygon (a flat shape with straight sides).
So, to be a polyhedron there should be no curved surfaces.
