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

Drag the vertices of the triangle to see how the sizes of the angles, the lengths[br]of the sides, and the sines of the angles vary.[br][br]Note that the ratio of the length of each side and the sine of the angle opposite[br]that side will not vary (for the unit circle, it will always be two)
