It is a 2-dimensional (plane) figure that is closed and which is bounded by straight lines.
A polygon must be a plane, closed figure bounded by straight lines.
A hexagon is a plane figure bounded by six straight lines. That is not the same thing as 6.
A pentagon is a plane figure bounded by five straight lines. It does not equal 180 of anything.
It is a plane shape bounded by six straight lines.
A plane figure cannot be bounded by only one straight line. If the shape is bounded by lines which are not straight or by several straight lines the answer will depend on exactly what these are.
It is a plane figure bounded by 400 straight lines.
