The sum of the interior angles of an n-gon is given by the formula (n-2)(180) where n is the number of sides of the polygon. Thus, the sum of the interior angles of an 18-gon is (18-2)(180) = 2880.
The sum of the interior angles of an n sided figure is (n-2)*180 degrees So for an 8 sided figure, the sum is 6*180 = 1080 degrees.
The sum of the measures of the angles in a figure having 9 sides is 20 degrees each angle.
To figure that out you must divide: 360 degrees / 54 = 6.67 degrees or 6 2/3 degrees
To find the sum of the interior angles of a heptagon, use the formula (n-2) times 180 over n, where n is equal to the number of sides of the polygon.For a heptagon, which is a 7-sided figure, we plug in values to get (7-2) times 180, or 5 times 180 degrees, or 900 degrees.
If you're talking a plane ie 2-dimensional figure, then like ALL four sided shapes, the interior angles total 360 degrees.
Exterior angles add up to 360 degrees Interior angles up to 2520 degrees
Exterior angles add up to 360 degrees Interior angles add up to 1620 degrees
No, a rectangle is not a figure with no angles. A rectangle is a quadrilateral with four right angles. Each angle in a rectangle measures 90 degrees. If a figure has no angles, it would be a circle, which has no straight lines or angles.
The interior angles of a heptagon add up to 900 degrees
The sum of the interior angles of an n sided figure is (n-2)*180 degrees So for an 8 sided figure, the sum is 6*180 = 1080 degrees.
540 degrees.
1080 degrees
The interior angles of every 4-sided figure add up to 360 degrees.
The sum of the measures of the angles in a figure having 9 sides is 20 degrees each angle.
A trapezoid is a quadrilateral, a figure with four sides. The sum of the interior angle measures of any quadrilateral is 360 degrees.
The 14 interior angles add up to 2160 degrees
It is 180x5=900 degrees
