Question

sum of the interior angles of a polygon using the formula (n - 2) × 180°. Why it is taken as -2 ?

Answer 1

Answer:

Not sure what all that extra stuff is but the formula to find interior angles is (n-2)180

Step-by-step explanation:

There is a -2 because 180 degrees accounts for 2 angles so you must take it away. I know that is confusing but think of a square, we know the sum of interior angles is 360 but without subtracting 2 angles, we would have 720 degress.

I dont completely understand the question so I apologize if I didnt answer you correctly
