A nonagon has 9 sides.
sum_of_interior_angles = (number_of_sides - 2) x 180o
= (9 - 2) x 180o
= 1260o
1345 * * * * * The above answer, submitted by the Answer Community is WRONG!
the sum of the interior angles of a convex 45-gon is 7740.
No, a convex polygon cannot have an interior angle sum of 400 degrees. The sum of the interior angles of a convex polygon is always equal to (n-2) * 180 degrees, where n is the number of sides. Since the sum of the interior angles must be greater than 180 degrees for each interior angle, a convex polygon with an interior angle sum of 400 degrees would require at least 9 sides, which would make it a nonagon, not a polygon.
The sum of the interior angles of a nonagon is 1260 degrees.
1260
1260 degrees
It depends on convex WHAT!
a convex polygon has 6 sides . What is the sum of the measure of its interior angles?
No. In a convex polygon the sum of the interior angles is (n-2)*180 deg where n is the number of interior angles. In a non-convex polygon this is not necessarily true.
the sum of the interior angles of a 35-gon.
900 degrees. And it does not have to be convex.
The sum of the interior angles of a nonagon is 1260 degrees. A nonagon is a nine-sided polygon in geometry. The formula to find the sum of interior angles in a polygon is given by the formula [n-2] x 180 degrees, where n represents the number of sides.
