प्रश्न
In the given figure, QS ⊥ PR, RT ⊥ PQ and QS = RT.
- Is ∆QSR = ∆RTO? Give reasons.
- Is ∠PQR = ∠PRQ? Give reasons.
उत्तर
i. In ∆QSR and ∆RTO,
∠OSR = ∠RTO = 90° ......(∵ QS ⊥ PR and RT ⊥ PQ (given))
QS = RT ......(Given)
QR = RO ......(Common hypotenuse)
∴ ∆QSR ≅ ∆RTQ ......(RHS criterion)
ii. Yes, by using (i) part, we get
∠TQR = ∠SRQ ......(By C.P.C.T)
⇒ ∠PQR = PRQ
