Question

IN ABparallel to QR , AB,=3cmQR=9cm and PR=6cm. Find PB​

Answer 1

Answer:

ANSWER

Given AB is 3 cm,PR is 2 cm PR is 6 cm

In △PAB and △PQR

∠PAB=∠PQR (corresponding angles)

and ∠P is common.

∴△PAB∼△PQR (AA similarity criterion)

Since corresponding sides are proportional,

QR

AB

=

PR

PB

QR=

PB

AB×PR

=

2

3×6

Thus, QR=9 cm.
