What is the relationship between the sides and angles in a triangle?

Back

In any triangle, the larger the angle, the longer the side opposite that angle. This relationship is fundamental in solving triangles using the Law of Sines and the Law of Cosines.

How do you determine if the Law of Sines or the Law of Cosines should be used?

Back

Use the Law of Sines when you have two angles and one side (AAS or ASA) or two sides and a non-included angle (SSA). Use the Law of Cosines when you have two sides and the included angle (SAS) or all three sides (SSS).
