प्रश्न
In the given figure, PQ || AB; CQ = 4.8 cm QB = 3.6 cm and AB = 6.3 cm. Find : PQ
उत्तर
In ΔCPQ and ΔCAB,
∠PCQ = ∠ACB ...(Since PQ || AB, so the angles are corresponding angles)
∠C = ∠C ...(Common angle)
∴ ΔCPQ ∼ ΔCAB ...(AA criterion for similarity)
`=> (PQ)/(AB) = (CQ)/(CB)`
`=> (PQ)/(6.3) = (4.8)/(8.4) `
So, PQ = 3.6
