Which is the formula for finding the sum of the interior angles of a polygon?

180 (n + 2) where n is the number of sides

180 (n - 2) where n is the number of sides

360 (n + 2) where n is the number of sides

360 (n - 2) where n is the number of sides

    It would be

    180 (n - 2) where n is the number of sides

    The number of sides would be 180 (n-2), we can test this theory with a triangle (interior angles add up to 180). A triangle has 3 sides so:

    180 (1) = 180

    Therefore, the aforementioned equation is valid!
