Answer

angles

Work Step by Step

From the Law of Sines $\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}$ with the measures of the angles $A$, $B$, $C$ given, we cannot solve the equations to find $a$, $b$, $c$. We need at least one of the triangle's sides measures. So when given all the three $\textbf{angles}$ there is no unique solution for the triangle (all similar triangles having those angles will fit).
