Question

sovlve this correctly​

Answer 1

Answer:

Given : a, b, and c are points of op, oq , or respectively such that

ab ll pq

ac ll pr

To prove : BC ll QR

Step-by-step explanation:

In triangle poq we have

ab ll pq

So by Thales theorem

oa/ap = ob/bq -------------------(1)

Similarly in triangle por we have

ac ll pr

so by Thales theorem

oa/ap =oc/or ---------------------------(2)

Equating equation 1 and 2 we get:

ob/bq=oc/or

Now by Converse of Thales theorem we get

BC ll QR

Hence proved
