 Hi and welcome to the session. I am Panika and I am going to help you to solve the following question. The question says which of the following figures lie on the same base and between the same parallels? In such a case write a common base and the two parallels. Before solving this question we should know that two figures are said to be on the same base between the same parallels have a A point as common base, B point as the vertices opposite to the common base of each figure lie on a line parallel to the base. Knowledge of this is the key idea in this question. Let's now begin with the solution. Clearly parallelogram p q s r p z m s r on the same base. So this verifies the A point. Now we will verify the B point. Now the vertices m and n of trimpezium m n s r and the vertices p and q of parallelogram p q s r opposite to the base s r does not lie on the same line. So we can say that these two figures does not lie between the same parallels. So since vertices of trimpezium s r and q parallelogram p q s opposite to the base on the same line two figures in parallel. This completes the session. Bye and take care.
