ΔABC is similar to ΔPQR. AB¯¯¯¯¯ corresponds to PQ¯¯¯¯¯, and BC¯¯¯¯¯ corresponds to
QR¯¯¯¯¯. If AB = 9, BC = 12, CA = 6, and PQ = 3, what are the lengths of QR¯¯¯¯¯ and RP¯¯¯¯¯?
a QR = 4, RP = 2
b QR = 6, RP = 4.5
c QR = 4.5, RP = 6
d QR = 2, RP = 4

Heya user ,
Here is your answer !!
ΔABC is similar to ΔPQR.
AB corresponds to PQ,
and BC corresponds to QR.
So, AC corresponds to PR .
Hence ,
AB/PQ = BC/QR = AC/PR .
GIVEN ,
AB = 9, BC = 12, CA = 6, and PQ = 3 .
ATQ ,
AB/PQ = BC/QR
=> 9/3 = 12/QR
=> QR = 4
Also,
AB/PQ = AC/PR
=> 9/3 = 6/PR
=> PR = 2 .
Hence ,
Answer is option (A) QR = 4, RP = 2 .
Hope it helps !!
