Given the side lengths of some triangle:


\begin{gathered} L_1=84 \\ L_2=96 \\ L_3=60 \end{gathered}

Let us suppose that there exists another triangle with these side lengths:


\begin{gathered} L_1^(\prime)=84 \\ L_2^(\prime)=96 \\ L_3^(\prime)=60 \end{gathered}

Based on these, we can say that:


\begin{gathered} L_1\cong L_1^(\prime) \\ L_2\cong L^(\prime)_2 \\ L_3\cong L^(\prime)_3 \end{gathered}

Then, using the Side-side-side theorem, we conclude that both triangles are congruent, so this triangle is unique
