Answer:

nonagon can have

6

diagonals drawn inside of it to form

7

interior triangles.

Every triangle's angles have a sum of

180

˚

. Therefore, since there are

7

triangles, the sum of the interior angles in a nine-sided polygon is

7

×

180

˚

=

1260

˚

This can be generalized to a polygon with

n

sides, since

n

−

2

triangles can be drawn in any polygon. Thus, the formula is

180

˚

(

n

−

2

)
