Exercise 9.1
Question :1 : Which of the following figures lie on the same base and between the same parallels? In such a case, write the common base and the two parallels.
Answer :
(i) Trapezium ABCD and ΔPDC lie on the same DC and between the same parallel lines AB and
CD.
(ii) Parallelogram PQRS and trapezium SMNR lie on the same base SR but not between the
same parallel lines.
(iii) Parallelogram PQRS and ΔRTQ lie on the same base QR and between parallel lines QR and
PS.
(iv) Parallelogram ABCD and ΔPQR do not lie on the same base but between the same parallel
lines BC and AD.
(v) Quadrilateral ABQD and trapezium APCD lie on the same base AD and between the same
parallel lines AD and BQ.
(vi) Parallelogram PQRS and parallelogram ABCD do not lie on the same SR but between the
same parallel lines SR and PQ.
