Question

ABCD is a parallelogram in which P and Q are mid-points of opposite sides AB and CD (see Fig. 8.18). If AQ intersects DP at S and BQ intersects CP at R, show that: (i) APCQ is a parallelogram.(ii) DPBQ is a parallelogram.(iii) PSQR is a parallelogram

Answer 1

ABCD is a parallelogram
PQ=CQ=1/2DC
AP=PB=1/2AB
`:.`AP=CQ=1/2AB
AB||CD
`:.`AB||CQ
SQ||PR(AQCP)
PS||QR(DPBQ)
