1. We know from the problem that there is a side of length 8\ \text{cm} 45^\circ 80^\circ
2. The total sum of internal angles of a triangle is180^\circ
180^\circ - 45^\circ - 80^\circ = 55^\circ
3. This gives us a unique set of angles:45^\circ, 80^\circ, 55^\circ
4. Since the corresponding angles in both triangles are equivalent, the triangles fall under the Angle-Angle-Angle (AAA) similarity criterion.
5. However, AAA similarity does not guarantee that the triangles are congruent. Congruence requires that the corresponding sides are congruent.
6. Because only one side of both triangles is given as8\ \text{cm}
Final Answer: The triangles are not necessarily congruent.
