Detailed Solution

Concept: Corresponding sides of are supposed to be proportional.When the ratios between the lengths of the respective sides of two triangles are the same and the corresponding angles are equal, the two triangles are said to be comparable. The corresponding sides of two comparable triangles are proportionate. The same two angle pairs are touched by corresponding sides. When the sides are equivalent, you may multiply each side by the same value to go from one triangle to another.
AA similarity (Angle – Angle similarity): When similarity is between corresponding angles of two triangles.
SSS similarity (Side –Side-Side similarity): When similarity is between corresponding sides of two triangles.
As we are considering only sides, therefore, SSS similarity is used.
Hence, the correct option is (1).
