Janice says that the sum of the measures of the interior angles of an octagon is 900. Is Janice correct? Why or why not? She's [B]incorrect. [/B] The interior angle sum for a polygon is found with this formula: Interior Angle Sum = (sides - 2) x 180 Since an octagon has 8 sides, we have: Interior Angle Sum = (8 - 2) x 180 Interior Angle Sum = 6 x 180 Interior Angle sum = 1080
