A 2-Dimensional closed lined figure is known as Polygon. The triangle is smallest polygon.
Following figures are not polygons
Perimeter of Polygon – Addition of length of all sides of polygon
Area of Polygon – The region bounded by polygon.
Regular Polygon – A polygon with all the sides equal in length as well as all the angles are also equal is known as Regular Polygon.
A polygon has ‘n’ numbers of sides and it can be divided into ‘n-2’ triangles.
The sum of measures of the interior angles of an n- sided polygon is = (n-2) x 180°.
