Let $$\theta$$ be an angle such that P is the terminal point of $$\theta$$:

Some of the points Q,S,R,T can be the terminal point of $$\theta$$/2.

Not sure what $$\theta$$/2 looks like, any advice?

The possible terminal points of $$\theta/2$$ are R and T.

no, that is incorrect, but why would R and T be equal to $$\theta$$/2

The angle $$\theta$$ goes anti-clockwise from the positive x-axis around to the red line.  The angle $$\theta/2$$ would go half-way (again in an anti-clockwise direction) from the positive x-axis towards the red line.  It would therefore get to point Q.

Thank you! That makes sense

Edit: I also noticed that point S is also a terminal point of $$\theta$$/2
