I have two angles:(adsbygoogle = window.adsbygoogle || []).push({});

[itex]θ[/itex]:

and [itex]θ_{1}[/itex]:

[itex]θ_{1}[/itex] = [itex]θ[/itex]

How do I differentiate the two angles? I want to say "leftward facing" and "rightward facing", but I'm not sure how to "mathematically." Note that I must talk about the angle that's between 0-90 degrees.

Thanks,

Ben
