In the Polygon Interior Angle Sum Theorem, what does $n$  represent?

• The measure of the largest interior angle

• The number of sides of the polygon

• Nothing

• The number of triangles that compose the polygon

The sum of the interior angles of a polygon is __________________ where n is the number of sides.

• (n - 2)180
• (n - 1)180
• 360
• (n - 3)(180)
