Question

In ∆PQR, E and F are points on sides PQ and PR respectively. PQ=1.28cm, PR=2.56cm, PE=0.18cm and PF=0.36cm. Show that EF∥QR. this question is from triangles class 10 solve it quick

Answer 1

Answer:

Step-by-step explanation:

this can be proved by converse of bpt theorem

for that we have to find whether EF divides sides PQ and PR in the same ratio

PE / PQ = PF / PR

0.18 / 1.28 = 0.36 / 2.56

by cross multiplication:-

0.4608 = 0.4608

Therefore, EF divides sides PQ and PR in the same ratio

so by converse of bpt, we can say that EF II QR
