Each angle of a rectangle is

In parallelogram ABCD the bisectors of $\mathrm{\angle }A\backslash angle\; A$ and $\mathrm{\angle }B\backslash angle\; B$ meet at ’O’. Then the value of ${\text{x}}^{\circ }\backslash text\{x\}^\backslash circ$ is

In $\mathrm{△}ABC\backslash triangle\; ABC$, BC = 8 cm and D, E are the midpoints of AB and AC; also AF = $\frac{1}{2}\backslash frac\{1\}\{2\}$AD and AG = $\frac{1}{2}\backslash frac\{1\}\{2\}$AE then FG =

In $\mathrm{△}ABC;\backslash triangle\; ABC;$ D, E and F are the mid points of the sides, then $ar(\mathrm{△}DEF)=ar(\backslash triangle\; DEF)=$

If the diagonals of a quadrilateral bisect each other then it is a

Two adjacent sides of a parallelogram are 4.7 cm and 6.3 cm then its perimeter is

If each pair of opposite angles are equal then it is a

In ABCD; AB = DC and AD = BC also $\mathrm{\angle }A={90}^{\circ }\backslash angle\; A=90^\backslash circ$ then ABCD is a
