Construct rhombus $\mathrm{HOME}$, where $\angle \mathrm{HOM}=60°$ and $\mathrm{HO}=6 \mathrm{cm}$.

Construct rhombus $\mathrm{ROAD}$, where $\mathrm{RA}=8 \mathrm{cm}$ and $\text{OD=6 cm}$.

Construct a parallelogram $\mathrm{GOLD}$, where $\mathrm{GO}=7 \mathrm{cm}, \mathrm{OL}=5.8 \mathrm{cm} \mathrm{and} \mathrm{GL}=5.8 \mathrm{cm}$.

$\mathrm{ABCD}$ is a rectangle if $\mathrm{AC}=5 \mathrm{cm}$, then what is the length of $\mathrm{BD}$ in $\mathrm{cm}$.

$\mathrm{PQRS}$ is a square, $\mathrm{PR}$ and $\mathrm{QS}$ are two diagonals intersecting at $O$. $\mathrm{PR}=5 \mathrm{cm}$. Find the length of $\mathrm{QO}$ in $\mathrm{cm}$.

Write the measurement of $\angle \mathrm{ADC}$ in a parallelogram $\mathrm{ABCD}$, where $\angle \mathrm{ABC}=60°$.

The diagonals $AC, BD$ of a rhombus $\mathrm{ABCD}$ are intersected at $\mathrm{O}$. Write the measurement of $\angle \mathrm{AOB}$.
