The Law of Sines and the Unit Circle

The applet demonstrates the law of sines. It shows a triangle inscribed within the unit circle. You can drag the vertices of the triangle around to change its shape. The size of each angle, its sine, and the length of the side opposite the angle are displayed in a table. The table is updated in real time.
