उत्तर
In the following figure, ∆ARO ≅ ∆PQO.
Explanation:
In ∆ARO and ∆PQO,
∠ARO = ∠PQO = 55°
∠AOR = ∠POQ ...[Vertically opposite angles]
∴ ∠RAO = ∠QPO ...[∵ If two angles of a triangle are equal to two angles of another triangle then the third angle is also equal]
AO = PO = 2.5 cm
∴ ∆ARO ≅ ∆PQO ...[ASA criterion]
