Question 2 (ii)
E and F are points on the sides PQ and PR respectively of a ΔPQR. For the following case, state whether EF || QR.
(ii) PE = 4 cm, QE = 4.5 cm, PF = 8 cm and RF = 9 cm
In ΔPQR, E and F are two points on the sides PQ and PR respectively.
(ii) PE = 4 cm, QE = 4.5 cm, PF = 8cm, RF = 9cm
∴PEQE=44.5=4045=89 [By using Basic proportionality theorem]
And,PFRF=89
So, PEQE=PFRF
Hence, EF is parallel to QR.
