The expression ( n - 2 ) is commonly used in geometry to determine the number of triangles that can be formed in a polygon with ( n ) sides. Multiplying ( n - 2 ) by 180 degrees gives the total sum of the interior angles of the polygon. Therefore, the formula for the sum of the interior angles of an ( n )-sided polygon is ( (n - 2) \times 180^\circ ).
