### The sides of a triangle are and for some .Then the greatest angle of the triangle is

The **law of cosines** generalizes the Pythagorean formula to all triangles. It says that *c*^{2}, the square of one side of the triangle, is equal to *a*^{2} + *b*^{2}, the sum of the squares of the the other two sides, minus 2*ab* cos *C*, twice their product times the cosine of the opposite angle. When the angle *C* is right, it becomes the Pythagorean formula.
