A decagon, with ten sides. The formula for sum of the interior angles of a polygon is 180(n-2), where n is the number of sides. From the problem statement, 1440 = 180n - 360, or n = 10.

A polygon with 10 sides is called decagon and the sum of the interior angles is 1440 degrees. (10-2)180=1440
A 10 sided decagon polygon has 10 interior angles that add up to 1440 degrees.
The interior angles of a 10 sided decagon add up to 1440 degrees
There are 1440 degrees in a decagon.To find the sum of the angles in a polygon, you use the formula n-2 multiplied by 180, where n is the number of sides the polygon has.
polygon cannot be formed because the angle between any two sides cannot be greater than 180 degrees. If you are asking for a polygon with total interior angles of 1440, you have a regular 10-sided figure, with each interior angle 144° ■
