Which of the following statement is correct about the AAS congruence of triangles?
1. If two angles of one triangle are congruent to the corresponding angles of the other triangle and the sides included between them are congruent, then two triangles are congruent
2. If the hypotenuse and one side of one triangle are respectively congruent to the hypotenuse and the corresponding side of the other triangle, then two right-angled triangles are congruent
3. If three sides of one triangle are congruent to the corresponding sides of the other triangle, then two triangles are congruent
4. If two sides of one triangle are congruent to the corresponding sides of other triangle and the angles include between them are congruent, then two triangles are congruent
