Answer the following questions related to triangle congruence criteria.
(i) State the Side–Angle–Side (SAS) criterion for congruence of two triangles.
(ii) Explain why, in this criterion, the equal angle must be the angle included between the two equal sides.
(iii) Two triangles have two pairs of corresponding sides equal and one pair of corresponding angles also equal, but the equal angle is not included between the equal sides. Are the two triangles necessarily congruent? Give a brief justification for your answer.
