What is the sum of angles in a 9-sided polygon?
(n-2)*180 = sum of interior angles of any polygon where n = number of sides. (9-2)*180 = 1260 degrees.
What regular polygon has the sum of its interior angles add up to 1260?
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
What is the angle sum of a polygon with 9 sides?
9099 * * * * * The sum of the interior angles is (9 - 2)*180 = 1260 degrees.
What polygon has the sum of 1260 as interior angles?
A nonagon which has 9 sides
What is the angle sum for an eleven sided polygon?
The formula for finding the sum of the interior angles of a polygon is: 180 x (n - 2) where n = the number of sides. This comes from knowing the following: Given a polygon of n sides, there are n - 2 triangles you can form by connecting a given vertice (point where two sides meet) to all other vertices of the polygon. The 180 in the formula is the sum of the angles in a triangle. Therefore, the sum of the interior angles (or, as you put it, the angle sum) of your 11 sided figure would be: 180 x (11 - 2) = 180 x (9) = 1620 degrees. Hope that answers your question and gets you on your way to figuring out other geometry problems.
What is the sum of the angles in a nine sided polygon?
If this 9 sided polygon is a regular polygon, then the sum of its angles is:(n - 2)180 degrees = (9 - 2)180 degrees = 7 x 180 degrees = 1,260 degrees.
What is the sum of angles in a 9-sided polygon?
(n-2)*180 = sum of interior angles of any polygon where n = number of sides. (9-2)*180 = 1260 degrees.
How many degrees in the sum of the cc interior angles of a nine sided polygon?
A 9 sided nonagon has 9 interior angles that add up to 1260 degrees
What regular polygon has the sum of its interior angles add up to 1260?
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
What is the sum of the interior angles of a nine sided polygon?
To find the sum of the interior angels of the formula (n-2)*180 is used. The 'n' represents the number of sides. The sum of he interior angles of a nine sided polygon would be (9-2)*180=1260.
What polygon has a sum of 1260?
A 9 sided nonagon has interior angles that add up to 1260 degrees
What is the sum of measure of a nonagon?
A nonagon is a 9 sided polygon and its 9 interior angles add up to 1260 degrees
What polygon has a sum of 1260 degrees?
A 9 sided nonagon has interior angles that add up to 1260 degrees
What is the exterior angle of a 9 sided polygon?
If its a regular 9 sided polygon then the exterior angles are 40 degrees.
What is the angle sum for a 9 sided polygon?
1620
What is a shap with 9 angles and 9 sides?
A nonagon is a 9 sided polygon having 9 interior angles
What is the sum of the angle s of a 9 sided shape?
The sum of the interior angles of an n-sided polygon (I presume that's what you mean), in degrees, is 180 * (n - 2). Here, n is 9 so the answer is 7 * 180 which is 1,260 degrees.
