Cosine theorem: In any triangle ABC is:											
a2 = b2 + c2 - 2bc cos a											
b2 = a2 + c2 - 2ac cos b											
c2 = a2 + b2 - 2ab cos g											
the square of the triangle is equal to the sum of the squares of the other parties											
reduced by twice the product of these parties and the cosine of the angle cordoned them.
