Q : 7 P and Q are respectively the mid-points of sides AB and BC of a triangle ABC and R is the mid-point of AP, show that
(iii)
QP is the median of ABQ
Therefore, ar(PBQ) = 1/2. (ar ABQ)
= (1/2). (1/2) (ar ABC) [since AQ is the median of ABC
= 1/4 (ar ABC)
= ar ( ARC) [from eq (A) of part (i)]
Hence proved
