WebSep 15, 2024 · The angle between two sides of a triangle is often called the included angle. Notice in the Law of Cosines that if two sides and their included angle are known (e.g. $b $, $c $, and $A$), then we have a formula for the square of the third side. We will now solve the triangle from Example $\PageIndex{2}$. Web7.2 1 The Law of Sines In this section we will solve triangles that are not necessarily right triangles.
