What are the best steps to solve the triangles of exercise 6.2 of class 10th math how i solve this question because it is very important E and F are points on the sides PQ and PR respectively of a ΔPQR. For each of the following cases, state whether EF || QR.(ii) PE = 4 cm, QE = 4.5 cm, PF = 8 cm and RF = 9 cm

      Given, PE = 4 cm, QE = 4.5 cm, PF = 8cm and RF = 9cm

      Therefore, by using Basic proportionality theorem, we get,

      PE/QE = 4/4.5 = 40/45 = 8/9

      And, PF/RF = 8/9

      So, we get here,

      PE/QE = PF/RF

      Hence, EF is parallel to QR.
