Yes, a regular polygon is a closed figure. It is defined as a polygon with all sides and angles equal, which forms a complete, enclosed shape. Examples of regular polygons include equilateral triangles, squares, and regular hexagons. Since they consist of straight line segments that connect back to the starting point, they inherently create a closed figure.
Yes, it is true.
The sum of the interior angles of a n-sided polygon is (n-2)*180 degrees. This is true whether or not the polygon is regular.

The circle has a smaller area than the polygon.
it's a closed figure with straight sides
a polygon is a shape with 5 corners A pentagon has five sides. A polygon has 3 or more sides, is closed and has line segments as the sides ( no curved sides ).
Only A (It is a closed figure) is true. The rest are incorrect because they define specific regular polygons. If you consider B (It is a quadrilateral), you must follow the logic that all quadrilaterals are polygons but not all polygons are quadrilaterals (an easier-to-follow example of this logic is: All fathers are male, but not all males are fathers).
