An octagon has eight sides, which means it also has eight angles. The sum of the interior angles of any polygon can be found using the formula (n-2) * 180 degrees, where n is the number of sides. For an octagon, this would be (8-2) * 180 = 1080 degrees. Each angle in a regular octagon measures 135 degrees.
