Law of sines and cosines. Sine and cosine rule by vhughes5 views. Great handout for students and teachers in PreCalculus, Trig, or even Algebra 2. In trigonometry, the law of cosines also known as Al-Kashi law or the cosine formula or cosine rule is a statement about the general triangles which relates the lengths of its sides to the cosine of one of its angles. Law of Cosines: Use if there is a known angle adjacent to two known sides and the question asks for. The Sines Theorem and the Cosines Theorem are "complementary".

Measurement and Geometry : Module 24 Year : PDF Version of module. In the module, Introductory Trigonometry , we showed that if we know the angles and one side in a right-angled triangle we can find the other sides using the trigonometric ratios sine, cosine and tangent. Similarly, knowing any two of the sides in a right-angled triangle enables us to find all the angles. Not all triangles contain a right-angle.
