In the given triangle P is the mid point of AB and PQ is || to BC.
(i)
In the quadrilateral PBCR,
BP // CR
BC // PR
(ii)
In the parallelogram PBCR
BP = CR
BP = AP { P is the midpoint of AB }
CR = AP
AB || CR and AC is transversal, ∠PAQ = ∠RCQ.
AB || CR and PR is tranversal, ∠APQ = ∠CRQ
In ΔAPQ and ΔCRQ
= > CR = AP, ∠PAQ = ∠RCQ and ∠APQ = ∠CRQ
= > ΔAPQ ≅ ΔCRQ
= > AQ = CQ.
Hope this helps!
