Question

In the following figure, AB || QR. Find the length of PB.

Solution

We have, ΔPAB and ΔPQR

∠P = ∠P [common]

∠PAB = ∠PQR [corresponding angles]

Then, ΔPAB ~ ΔPQR [By AA similarity]

`therefore"PB"/"PR"="AB"/"QR"`      [Corresponding parts of similar Δare proportional]

`rArr"PB"/6=3/9`

`rArr"PB"=3/9xx6=2` cm

  Is there an error in this question or solution?
