Give the properties common to both a parallelogram and a rectangle

$\mathrm{PINK}$ is a rhombus with $\angle \mathrm{IPK}=64°$. Find $\angle \mathrm{IKN}$.

$\mathrm{SNAP}$ is a parallelogram in which $\angle \mathrm{PSO}=50°$ and $\angle \mathrm{NSO}=25°$ and $\angle \mathrm{AOP}=60°$. Find $\angle \mathrm{SNO},\angle \mathrm{OPA},\angle \mathrm{SAN}$ and $\angle \mathrm{ANP}$.

In the given figure, find the measure of $\angle \mathrm{UMP}$.

The bisectors of $\angle \mathrm{A}$ and $\angle \mathrm{B}$ meet at point $\mathrm{P}$. If $\angle \mathrm{C}=105°$ and $\angle \mathrm{K}=55°$, find the measure of $\angle \mathrm{APB}$
