Show that BC/QR.​

Answer 1

Answer:

refer attachment for ans

Step-by-step explanation:

In △OPQ, we have

AB∥PQ

Therefore, by using basic proportionality theorem , we have

AP

OA

=

BQ

OO(i)

IN △OPR, we have

AC∥PR

Therefore, by using basic proportionality theorem , we have

CR

OB

=

AP

OA (ii)

Comparing (i)&(ii), we get

BQ

OB

=

CR

OC

Therefore, by using converse of basic proportionality theorem, we get

BC∥QR
