3. POLYGON
●It is a closed figure made up of line segments that intersect only
at their endpoints.
●It comes from the Greek word poly which means “many” and
gonia which means “angle”.
●It can have at least 3 sides. The sides of a polygon do not cross
each other between their endpoints. Each endpoint where two
sides meet is called vertex.
