To find the sum of the interior angles of a hexagon, use the formula180(n-2) where n is 6 so180(4)=720 degrees.To find the measure of one angle in the regular hexagon, divide that number by 6 and Hexagon is defined as the polygonal figure having six sides and six angles. Also, The sum of all the interior angles of hexagon is 720 degrees. HEXAGON: Using the same methods as for hexagons to the right (I'll let you do the pictures)... To find the sum of the interior angles of a heptagon, divide it up into triangles... There are five triangles... Because the sum of the angles of each triangle is 180 degrees... We get. So, the sum of the interior angles of a heptagon is 900 degrees. Sum of the Interior Angles of a Regular N-gon. An interior angle is defined as the angle inside of a polygon made by two adjacent sides. The sum of the interior angles of a polygon is directly So, the sum of the interior angles of a hexagon is 720 degrees. Regular Hexagons: The properties of regular hexagons: All sides are the same length (congruent) and all interior angles are the same size (congruent). The sum of the interior angles of a hexagon is 720⁰. This concept can be extended and generalized. You will always end up with two less triangles than original sides. So the interior angle sum formula is: Interior Angle Sum = (n - 2)x 180⁰; where n is the number of sides. Sum of Interior Angles of a Polygon Regular polygons exist without limit (theoretically), but as you get more and more sides, the polygon looks more and more like a circle. The regular polygon with the fewest sides -- three -- is the equilateral triangle. This way, we can see that the sum of the 6 interior angles of a hexagon is (180+180+360) or 720 degrees. Given that a hexagon has 6 interior angles which are equal in measure, we find that each angle is equal to 720/6 or 120 degrees. If it is a Regular Polygon (all sides are equal, all angles are equal) Shape Sides Sum of Interior Angles Shape Each Angle; Triangle: 3: 180° 60° Quadrilateral: 4: 360° 90° Pentagon: 5: 540° 108° Hexagon: 6: 720° 120° Heptagon (or Septagon) 7: 900° 128.57...° Octagon: 8: 1080° 135° Nonagon: 9: 1260° 140°..... Any Polygon: n (n−2) × 180° (n−2) × 180° / n To do this, subtract 2 from the number of sides, and multiply the difference by 180. This will give you, in degrees, the sum of the interior angles in your polygon. For example, to find out the sum of the interior angles of a hexagon, you would calculate: s u m = ( 6 − 2) × 180 {\displaystyle sum= (6-2)\times 180}
