What is a regular polygon? State the name of a regular polygon of $6$ sides.

Find the angle measure of $x$ in the given figure.

Find the value of $x$ in the given figure.

The angle measure in the given figure is $x°$. Find the value of $x$.

If each angle in the given figure, measure $x°$, then find the value of $x$.

From the figure, if $x+y+z=k°$ then the value of $k$ is

What is the sum of the measure of its exterior angles $\mathrm{x}, \mathrm{y}, \mathrm{z}, \mathrm{p}, \mathrm{q}, \mathrm{r}$? Write the answer in degrees.

Is $\mathrm{x}=\mathrm{y}=\mathrm{z}=\mathrm{p}=\mathrm{q}=\mathrm{r}$? Why?
