 Hi and welcome to the session let us discuss 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 the common base and the two parallels now this is the sixth figure given to us let's now begin with the solution now first of all consider palelogram a q s r palelogram a st now both these palelograms are on the same base p s but the vertices of the palelogram p a st that is a and d and vertices q and r of p q r s does not lie on the same line so as the vertices opposite to the common base does not lie on the same line therefore these two palelograms does not lie between the same parallels now consider palelograms p q r s and b q r c now clearly both these palelograms are on the same base q r but the vertices of both these palelogram that is b and c of p q c r and p and s of p q r s does not lie on the same line therefore these two palelograms does not lie between the same parallels now consider palelograms a b c d p q r s clearly clearly both these palelograms does not have common base there exists no figure which lie on the same base and between the same parallels this completes the session bye and take care
