The animation or the triangle?
I posted that triangle to see if anyone was interested because,
long ago it was realized that knowing an angle or a side length was often
needed.
Not surprisingly 8 people did not request to see it. I figured most educated
types know their stuff.
I find it impossible to memorize all the sine/cosine law calculations.
