In `Delta ABC` the lines are drawn parallel to BC,CA and AB respectively through A,B and C intersecting at P, Q and R. Find the ration of perimeter of `Delta PQR` and `DeltaABC`

Text Solution

Verified by Experts

With the given details, we can create a diagram.
Please refer to video to see the diagram.
It is given that `PQ || BC and PR||AC`
`:. PA||BC and PB||AC`
It mean `APBC` is a parallelogram.
`:. AC = PB, AP = BC`
It means, all sides of `Delta APB and Delta ABC` are equal
So, their parimeters will be equal.
