To find the sum of the interior angles of an octagon, you can use the formula:
Sum = (n - 2) * 180 degrees,
where "n" represents the number of sides of the polygon. In this case, an octagon has 8 sides.
So, the sum of the interior angles of an octagon can be calculated as follows:
Sum = (8 - 2) * 180 degrees = 6 * 180 degrees = 1080 degrees.
Therefore, the sum of the interior angles of an octagon is 1080 degrees.
