Answer:
Step-by-step explanation:
Given:PQ||BC
PR||AC
P is the midpoint of AB
AB=12cm
To Prove: find QR
Construction: join QR such that QR||PB
Solution :
PQ is parallel to QR
QR is parallel to PB(by construction )
Therefore pqrb is a parallelogram
AB=12 cm
1/2 AB = 6cm
PB = 1/2 AB
PB=6 cm
PB=QR
PB|| QR
therefore QR= 6cm
