The Law of Sines
... There are three possible configurations that will enable us to use the Law of Sines. They are shown below. You don’t have an angle and side opposite it here but can easily find the angle opposite the side you know since the sum of the angles in a triangle must be 180°. ...

... • The interior angle sum S for a polygon with n sides is S = (n – 2) × 180°. In a regular polygon all the angles are equal, so each interior angle equals S divided by n. Since the interior and exterior angles are on a straight line, the exterior angle can be found by subtracting the interior angle f ...
