Properties of a Parallelogram

Shape made by the bisectors of angles of a parallelogram is

If the length of parallel sides of a parallelogram is $\mathrm{m}$ and $\mathrm{n}$, each, then the perimeter is equal to:

Parallelograms on the same base and between the same parallel sides are:

The interior opposite angles of a parallelogram are:

If the base of parallelogram is $10 \mathrm{cm}$ and its corresponding height is $5 \mathrm{cm}$, then the area of parallelogram is:

Is a square a parallelogram?

Two adjacent angles of a parallelogram are $(2x+25)°$ and $(3x-5)°.$ The value of $x$ is

If one of the angles of a parallelogram is $80°$, then the value of opposite angle is

Diagonals of a parallelogram are of equal length and intersect at right angle, then the parallelogram is

The lengths of the diagonals of a rhombus are $24 \mathrm{cm}$ and $18 \mathrm{cm}$ respectively. If the length of each side of the rhombus is $k \mathrm{cm}$, find the value of $k$.

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 $k$. 

 In the adjoining figure, $ABCD$ is a parallelogram in which $\angle BAO=35°,\angle DAO=40°$ and $\angle COD=105°$. If $\angle CBD=y°$, find the value of $y$.

 In the adjoining figure, $ABCD$ is a parallelogram in which $\angle BAO=35°, \angle DAO=40°$ and $\angle COD=105°.$ If $\angle ODC=k^{\circ }$, then find the value of $k$.

In the adjoining figure, $\mathrm{ABCD}$ is a square. A line segment $\mathrm{CX}$ cuts $\mathrm{AB}$ at $\mathrm{X}$ and the diagonal $\mathrm{BD}$ at $\mathrm{O}$ such that $\angle \mathrm{COD}=80°$ and $\angle \mathrm{OXA}=x°$. Find the value of $x$. (Give the answer in value without degree symbol).
