When you know the values for two or more sides of a triangle, you can use the law of cosines. In the following case, you know all three sides (which is called SSS, or side-side-side, in trigonometry) but none of the angles.

The Law of Cosines can be used to solve for the sides and angles of an oblique triangle when the following measurements are known: Three sides: SSS (side-side-side) Two sides and an included angle: SAS (side-angle-side)
