Read the following statements carefully and state $‘T\text{'}$for true and $‘F’$for false.
(i) Diagonals of a parallelogram are perpendicular to each other.
(ii) All four angles of a quadrilateral can be obtuse angles.
(iii) If all sides of a quadrilateral are equal, then it is a rhombus.

In the given figure (not drawn to scale), $ABCD$ and $PQRS$ are parallelograms. Find the value of $x$.

``

A quadrilateral is a parallelogram then

A quadrilateral can be a square if

In the given figure, $ABCD$ is a parallelogram, $M$ is the midpoint of $BD$ and $BD$ bisects $\angle B$ as well as $\angle D$. Then, $\angle AMB=?$

A quadrilateral can be a parallelogram if

A quadrilateral can be a rectangle if

A quadrilateral is a rhombus if

Is the parallelogram $ABCD$ a square? If
I. Diagonals of the parallelogram $ABCD$ are equal.
II. Diagonals of the parallelogram $ABCD$ intersect at right angles.

The correct answer is:

A quadrilateral can be a rhombus if
