In trapezium $ABCD$, $AB$ $\parallel$ $DC$. If $\angle D=x°$, then $\angle A=($_____$)°$.

Every diagonal in a parallelogram divides it into _____ triangles.

In parallelogram $ABCD$, its diagonals $AC$and $BD$ intersect at $O$. If $AO$= $5 \mathrm{cm}$, then $AC$= _____$\mathrm{cm}$.

In a rhombus $ABCD$, its diagonals intersect at $O$ . Then $\angle AOB=$_____$°$. 

$ABCD$ is a parallelogram then $\angle A$–$\angle C$= _____$°$

In a rectangle $ABCD$, the diagonal $AC$$=$ $10 \mathrm{cm}$, then the diagonal $BD$$=$ _____ $\mathrm{cm}$

In a square $ABCD$, the diagonals $AC$ and $BD$ are drawn. Then $\angle BAC$ $=$ _____$°$
