The sum of the interior angles of any polygon can be determined using the formula:
Sum = (n-2) * 180
where n is the number of sides of the polygon.
For a hendecagon (11-sided polygon), the sum of the interior angles is:
Sum = (11-2) * 180 = 9 * 180 = 1620 degrees.
Find the sum of the interior angles of a hendecagon (11-sided polygon).
