ANY n-sided polygon has interior angles that sum to 180(n - 2) degrees. For an octagon this is 180 x 6 ie 1080 degrees (so the individual interior angles of a regular octagon are 135 degrees).
find the sum of the measures of the interior angles of 13-gon.
Each interior angle of a regular hexagon measures 120 degrees. It has a total of 720 degrees of interior angles and a total of 360 degrees of exterior angles.
(number of sides - 2)*180 = total sum of interior angles
The sum of the interior angles add up to 3240 degrees.

find the sum of the measures of the interior angles of 13-gon.
It is an octagon each of whose sides is 5 cm long and each of whose interior angles measures 135 degrees.

Each interior angle of a regular hexagon measures 120 degrees. It has a total of 720 degrees of interior angles and a total of 360 degrees of exterior angles.
Total sum of interior angles: (37-2)*180 = 6,300 degrees
To find interior angle measurements, you must divide the shape into triangles by drawing diagonal lines. The diagonal lines draw triangles, and the interior angle measure of triangles are always 180 degrees. The sum of interior angles of an octagon is 1080 degrees. How ever many triangles you have, multiply it by 180. See octagons in the link for more help,

(8-2)*180 = 1080 degrees
Type your answer here... The sum of the angles in all polygons is 360 degrees. Thus, if you know the measure of the interior angles you can divide 360 by the measurement to find out how many interior angles and sides there are.
it equals to 3420 degrees
