Question

If a point R lies between two points P and Q such that PR=QR, then prove that PR=1/2PQ.

Answer 1

Here pq is a line segment and c is it's mid point
To prove: pr=1/2pq
Proof:r is the mid point of pq
Pr=rq
=Pr+pr=rq+pr
2pr=rq
(2pr)/2 =pq/2(divide 2 on both sides)
Therefore pr= 1/2pq

Answer 2

**Hey buddy here is ur answer..
=>PQ= PR +RQ
=>PQ=PR+PR(PR=RQ)
=>PQ=2PR
=>1/2PQ =PR
Hence proved..**
