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°

Polygons
Using various input scenarios of a polygon such as side length, number of sides, apothem, and radius, this calculator determines Perimeter or a polygon and Area of the polygon. This also determines interior angles of a polygon and diagonals of a polygon as well as the total number of 1 vertex diagonals.
