R. D. Sharma Solutions for Chapter: Quadrilaterals, Exercise 6: MULTIPLE CHOICE QUESTIONS (MCQs)

The opposite sides of a quadrilateral have

The consecutive sides of a quadrilateral have

$\mathrm{PQRS}$ is a quadrilateral. $\mathrm{PR}$ and $\mathrm{QS}$ intersect each other at $\mathrm{O}$. In which of the following cases, $\mathrm{PQRS}$ is a parallelogram?

$P$ is the midpoint of side $BC$ of a parallelogram $ABCD$ such that $\angle BAP=\angle DAP$. If $AD=10 \mathrm{cm}$, then $CD=$

In $∆ABC, E$ is the midpoint of median $AD$ such that $BE$ produced meets $AC$ at $F$. If $AC=10.5 \mathrm{cm}$, then $AF=$

$ABCD$ is a parallelogram and $E$ is the midpoint of $BC$. $DE$ and $AB$ when produced meet at $F$. Then, $AF=$

In a quadrilateral $ABCD, \angle A+\angle C$ is $2$ times $\angle B+\angle D$. If $\angle A=140°$ and $\angle D=60°$, then $\angle B=$?

The diagonals $AC$ and $BD$ of a rectangle $ABCD$ intersect each other at $P$. If $\angle ABD={50}^{°}$, then $\angle DPC=$
