I'm assuming that you need to know the number of triangles so you can find the sum of the interior angles (since each triangle has 180˚, all you have to do is multiply). If I'm correct in my assumption about your reason, then just remember that you'll always subtract 2 from the number of sides before multiplying by 180.
