The law of cosines generalizes the Pythagorean theorem, which holds only for right triangles: if the angle γ is a right angle (of measure 90° or π/2 radians), then cos γ = 0, and thus the law of cosines reduces to the Pythagorean theorem: [Math Processing Error] The law of cosin...
The Law of Cosines has been used for centuries by mathematicians and scientists to solve a variety of problems. It is an invaluable tool for those who need to calculate the size and shape of objects in the physical world. For example, it can be used to calculate the size of a triangle ...
The Law of Sines One method for solving for a missing length or angle of a triangle is by using the law of sines. The law of sines, unlike the law of cosines, uses proportions to solve for missing lengths. The ratio of the sine of an angle to the side opposite it is equal for ...

The law of sines establishes the relationship between the sides and angles of an oblique triangle(non-right triangle). Law of sines and law of cosines in trigonometry are important rules used for "solving a triangle". According to the sine rule, the ratios of the side lengths of a triangle...
