Question 67
Fill in the blanks to make the statement true.
In the given figure, ΔARO≅Δ
In ΔARO and ΔPQO,∠AOR=∠POQ [vertically opposite angles]
∠ARO=∠PQO=55∘ [given]
⇒∠RAO=∠QPO [Since if two angles of one triangle is equal to the two angles of other triangle then their third angle will also be equal]
Now, in ΔARO and ΔPQO,∠AOR=∠POQ [vertically opposite angles]
AO = PO = 2.5 cm
∠RAO=∠QPO [proved above]
By AAS congruence criterion, ΔARO≅ΔPQO
