How to plot the polar equation theta = pi/6 on wolframalpha I need to plot the polar equation 
theta = pi/6
My question has two parts.
1) Is it a line? I'm pretty sure it is, since the angle theta in the polar equation is a constant, but since I was not able to plot this on wolframalpha, I'm not 100% sure and I would like to confirm this.
2) How do I plot this on wolframalpha? I know that I can write polar plot $r = \sin (\theta)$`, for exeample and this will give me a circle, as it should. But if $\theta = pi/6$ is a line, writing polar plot theta = $\pi/6$ gives me the wrong answer. 

Since $r$ does not depend on $\theta$ trying  to graph it in polar coordinate is not possible. Since the slope of your graph is $\tan (\theta)$,you may try to graph it in Cartesian coordinates $y=\dfrac x{\sqrt 3}$ and let $x\ge 0.$
