## Law of Cosines Calculator

In trigonometry, the law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles. Using notation as in Fig. 1, the law of cosines states c 2 = a 2 + b 2 − 2 a b cos ⁡ γ, {\displaystyle c^{2}=a^{2}+b^{2}-2ab\cos

## Law of Cosines Calculator

The Law of Cosines is a generalization of the Pythagoras theorem, which holds only for right-angled triangles. If the angle C is 90⁰, then cos C=0. Then the Law of Cosines reduces to $$c^2=a^2 + b^2$$ Properties of a triangle Given below
