Question

if a point Q lies between two points p and R such that pq and qr prove that PQ =1/2qr

Answer 1

given the point q is the mid point of p and r so pq=qr
so pq+qr=pr
pq +pq=pr
2pq =pr
pq =¹/²pr

Answer 2

question is wrong because
Q ia mid point
I change the question
PQ=1÷2PR
PQ=QR
THEN PR=PQ+QR
PR=PQ+PQ. {PQ=QR}
PR=2PQ
PQ=PR÷2
