What is the sum of the degree measures of the interior angles of a hepyagon?

The sum of the degree measures of the interior angles of a polygon can be calculated using the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For a heptagon, which has 7 sides, the calculation is ( (7 - 2) \times 180^\circ = 5 \times 180^\circ = 900^\circ ). Therefore, the sum of the interior angles of a heptagon is 900 degrees.
