Hello sir what is the best way for solving the question of class 9th of Areas of Parallelograms and triangles of exercise 9.1 of math of question no.1, Give me the best and simple way for solving this question Which of the following figures lie on the same base and in-between the same parallels? In such a case, write the common base and the two parallels.
(i) Trapezium ABCD and ΔPDC lie on the same DC and in-between the same parallel lines AB and DC.
(ii) Parallelogram PQRS and trapezium SMNR lie on the same base SR but not in-between the same parallel lines.
(iii) Parallelogram PQRS and ΔRTQ lie on the same base QR and in-between the same parallel lines QR and PS.
(iv) Parallelogram ABCD and ΔPQR do not lie on the same base but in-between the same parallel lines BC and AD.
(v) Quadrilateral ABQD and trapezium APCD lie on the same base AD and in-between the same parallel lines AD and BQ.
(vi) Parallelogram PQRS and parallelogram ABCD do not lie on the same base SR but in-between the same parallel lines SR and PQ.
