Solution:
(i) ∆PDC and quadrilateral ABCD are on DC. They are in between AD || DC.

(ii) Parallelogram PQRS is on base SR. Trapezium SRMN is on base SR. But they are not in S between SR || PQ.

(iii) Parallelogram PQRS and ∆TRQ are on the base RQ and in between PS || RQ.

(iv) Parallelogram ABCD is on base BC and in between AD || BC.
∆RQP is on base PQ and in between AD || BC.
∴ Parallelogram ABCD and ∆RQP are not on the same base. But they are in between AD || DC.

(v) Here,
AD || DC,
AD || BC,
AP || DQ.
AD || PQ.
Parallelogrm ABCD and Parallelogram APQD are on same base AD and in between AD || BC.

(vi) Here, PQ || SR, PS || AD || BC || QR.
These are on the same base and in between a pair of parallel lines.
