In triangle ABC,PQ||BC,AP=2,PB=6,AQ=3,QC=9.Prove thatBC=4PQ

yajat1810: sorry bro

yajat1810: your question is wrong

yajat1810: it is that what i proved in the solution

Answered by yajat1810

draw a diagram like this
here AP = 2cm
PB = 6cm
AP/PB = 2/6 = 1/3
AQ = 3cm
QC = 9cm
AQ/QC = 3/9 = 1/3
AP/PB = AQ/QC
So, here ∆APQ is similar to ∆ABC
so, PQ/BC = 1/3
PQ×3 = BC

sneha536147: Read question again? figure is right

yajat1810: yes

yajat1810: but i said of question

sneha536147: We want to prove BC=4PQ

yajat1810: this question is wrong

yajat1810: what i sais is this mate

yajat1810: said*

sneha536147: It's impossible

sneha536147: I think Basic proportionality Theorem is useful here
