The triangles are congruent by AAS postulate ( option 4)
Congruent triangles are triangles with equal angles and equal corresponding side lengths.
The triangles can be stated to be congruent by what is given on them . For example SSS postulate , AAS postulate or SAS postulate.
In the diagram above ;
There are two equal angles marked and a corresponding side marked.
Therefore we can say that the triangles are congruent by AAS postulate i.e Angle Angle Side postulate.
