The Sine Law

We can use the pythagorean theorem or trigonometry (SohCahToa) to find the missing side or angle in any right triangle. But what about triangles that don't have a right angle? Well, that's when we use the sine law. Watch this to see how the sides and angles in any non-right triangle are related.

Here you can review the sine law, watch a few animations of how it works and try a brief quiz (3 questions). You can try another quiz (5 questions) over there.

Woohooo! The 100th Post!!
