Triangles have 3 interior angles that measure 180 degrees total.
The 4 interior angles add up to 360 degrees
(number of sides - 2)*180 = total sum of interior angles
The interior angles measure 360 degrees.
Interior angles total 2520 degrees
Sadly, there is no such shape. There is a heptagon or an octagon but a hectogon simply does not exist. And, since it does not exist, it has no interior angles. And since there are no interior angles, there is no total measure for them. I suggest you check out a mathematical site or a dictionary and figure out what you want and re-post the corrected question.
The interior angles of an octagon add up to 1080 degrees 1080 degrees in total, 135 each.
Interior angles = 360 degrees Exterior angles = 360 degrees
Exterior angles 360 degrees Interior angles 1260 degrees
what is the total of interior angles of the nonagon
No because the total sum of interior angles of a parallelogram are 360 degrees.
If you're talking a plane ie 2-dimensional figure, then like ALL four sided shapes, the interior angles total 360 degrees.
