Two parallelogram ABCD and ABEF are equal in area, they lie between the same parallel lines:
Yes
No
Nothing can be said
Answer
While it is a known geometric theorem that parallelograms on the same base and between the same parallels are equal in area, the converse is not strictly true in the way this question is phrased.
In above case both parallelograms share the base AB. However, simply having the same area and the same base does not automatically mean they must lie between the same parallels unless it is specified that they are on the same side of the base.
Thus, nothing can be said.
Hence, option 3 is the correct option.
