What is a formula for a hexagon? In a hexagon, the sum of all 6 interior angles is always 720º. The sum of interior angles of a polygon is calculated using the formula,(n-2) × 180°, where 'n' is the number of sides of the polygon. Since a hexagon has 6 sides, taking '...
9-sided polygon is called a nonagon and a 10-sided polygon is the decagon. nonagon shape a nonagon contains 9 straight sides and 9 vertices connecting these sides. the sum of all the interior angles of a nonagon is equal to 1260 degrees. the above figure shows the shape of a nonagon th...
