Question

In which of the following figures, two polygons lie on the same base and between the same parallel lines.

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

Explanation of the correct option.

Find the required polygon.

We know that one property of the polygons sharing common base is that vertex opposite to the common base of each figure must lie on a line parallel to the base.

In Figure $\mathrm{d}$ both parallelograms $\mathrm{APQR}$ and $\mathrm{QBSR}$ share a common base $\mathrm{QR}$ and lie between same parallel lines $\mathrm{PS}\parallel \mathrm{QR}$.

Hence Option D is the correct answer.
