The sum of the interior angles of a n-sided polygon is (n-2)*180 degrees. This is true whether or not the polygon is regular.
The interior angles of a polygon (regular or not) with n sides sum to (n - 2)*180 degrees.
It is: (number of sides -2)*180 = sum of interior angles If its a regular polygon then: sum of interior angles/number of sides = each interior angle
The sum of interior angles: (13-2)*180 = 1980 degrees
360 ________________________________________________ Sum of Interior Angles of a Polygon = 180 (n-2) Sum of Exterior Angles of a Polygon = 360 The sum of an angle and an exterior angle of a regular polygon is 360
A Regular Polygon
The sum of the interior angles of a n-sided polygon is (n-2)*180 degrees. This is true whether or not the polygon is regular.
The sum of the interior angles of an n-sided polygon is 180n - 360 degrees.
The interior angles of a polygon (regular or not) with n sides sum to (n - 2)*180 degrees.
There is no regular polygon with an interior angle of 20o. If the interior angle is 120o then there are six sides and the sum of the angles is 720o.
Me no no:(
It is: (number of sides -2)*180 = sum of interior angles If its a regular polygon then: sum of interior angles/number of sides = each interior angle
(number of sides-2)*180 = total sum of interior angles
The sum of interior angles: (13-2)*180 = 1980 degrees
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees.
15 sides
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
