WebTo represent the evaluation of the square root in phasor form, you put the angle inside the range $(-180^\circ,180^\circ]$ before halving it. So any angle in $[0^\circ,180^\circ]$ can be divided by 2 as-is, while any angle $\phi$ in $(-180^\circ,0]$ must be converted to $\phi-360^\circ$ and then halved. $\endgroup$
