Ley del Seno

proporción existente entre los lados y senos de los ángulos de un triángulo.

a/sen(a) = b/send(b) = c/sen(c)

2

Ley del coseno

el cuadrado de un lado es igual a la suma de los cuadrados de los lados restantes menos el cos del lado elegido por el producto de los lados restantes.

a²=c²+b²-2cos(a)×c×b
