**Statement of the law of cosines **(also known as the **al-Kashi's theorem**)**:** *the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them.*

In the above triangle, we can apply the **law of cosines** on each side :
