How do you solve an aaa triangle? explain.

From what I know ASA: You are given two angles and the included side. SSA: You are given two sides and the angle opposite one of them. SAS: You are given two sides and the included angle. AAA: It is not possible to solve a triangle given only the angles.But,now you can use a mixture of many different rules to solve these triangles, but it is generally thought that for the first three options (AAS, ASA, SSA) it is easiest to use the Law of Sines, and for the remaining possibilities (SAS, SSS) it is easiest to use the Law of Cosines. ,

The answer is why would a teacher ask that
