NCERT Solutions for Class 9 Maths Chapter 9 Exercise 9.1 – Areas of Parallelograms And Triangles

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.

Solution:

Here,  ∆PCD and trapezium ABCD lies on the same base and between same parallels.
Same base : CD
Same Parallels : AB & CD

Here, trapezium MNRS and //gm PQRS are on the same base but not lies between the same parallel lines.
So, here the required case is not observed.

Here, ∆TQR and //gm PQRS are on the same base and lie between the same parallel lines.
Same base :  QR
Parallel lines :  PS  &  QR.

Here, ∆ PQR and //gm ABCD lies betwen the same parallel lines but not on the common base.
So, here the required case is not observed.

Here, //gm ABCD and //gm APQD lies on the same base and lies between the same parallel lines.
