उत्तर
In the following figure, ∆PQR ≅ ∆XZY.
Explanation:
In ∆PQR and ∆XZY,
PQ = XZ = 3.5 cm
QR = ZY = 5 cm
∠PQR = ∠XZY = 45°
By SAS congruence criterion,
∆PQR ≅ ∆XZY

Given below are measurements of some parts of two triangles. Examine whether the two triangles are congruent or not, by using the SAS congruence rule. If the triangles are congruent, write them in symbolic form.
∆ABC, AB = 4.5 cm, AC = 4 cm, ∠A = 60°.
∆DEF, DE = 4 cm, FD = 4.5 cm, ∠D = 55°.
Consider the given pairs of triangles and say whether each pair is that of congruent triangles. If the triangles are congruent, say ‘how’; if they are not congruent say ‘why’ and also say if a small modification would make them congruent:
