The sum of the interior angles of any shape that has straight sides is
(180 degrees) times (the number of sides - 2) .
For the case of a hexagon, (the number of sides - 2) = 4 .
The sum of the interior angles = (180) x (4) = 720 degrees.
The sum of the exteior angles is always 360 degrees, no matter
how many sides the shape has.
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 we have 120 degrees. A regular hexagon has 6 angles of 120 degrees. The sum is 720 degrees.
A hexagon cannot have a sum. There can be the sum of its interior angles, its exterior angles, its side lengths, its area (and that of some other area), or other characteristics, but not of a hexagon.
The total. sum of the interior angles of a hexagon are 720 degrees.
Sum of included angles of any polygon = (180 x n) - 360 (where n is number of sides). For a hexagon the sum is (180 x 6) - 180 = 720 degrees.
Sum of angles in a polygon is (n -2)180. Hexagon has six sides. So the sum of angles is (6- 2)180. (4)180 =720
