MULTIPLE-CHOICE QUESTIONS (MCQ)

$ABCD$ is a rhombus such that $\angle ACB=50°.$ Then, $\angle ADB=?$

In which of the following given quadrilaterals are the diagonals equal?

If the diagonals of a quadrilateral bisect each other at right angles then the figure is a

The lengths of the diagonals of a rhombus are $16 \mathrm{cm}$ and $12 \mathrm{cm}$. The length of each side of the rhombus is

The length of each side of a rhombus is $10 \mathrm{cm}$ and one of its diagonals is of length $16 \mathrm{cm}$. The length of the other diagonal is

In a quadrilateral $PQRS$, opposite angles are equal. If $SR=2 \mathrm{cm}$, $PR=5 \mathrm{cm}$ and $PQ=k \mathrm{cm}$, then find the value of $k$. 

If $D$ and $E$ are respectively the midpoints of the sides $AB$ and $BC$ of $∆ABC$ in which $AB=7.2 \mathrm{cm}, BC=9.8 \mathrm{cm}$ and $AC=3.6 \mathrm{cm}$ and the length of $DE=k \mathrm{cm}$ then find $k$.

In a quadrilateral $PQRS$, the diagonals $PR$ and $QS$ bisect each other. If $\angle Q=56°$ and $\angle R=k°$, find the value of $k$.
