Information about Phase Angle
In the context of vectors and phasors, the term phase angle refers to the angular component of the polar coordinate representation. The notation 
for a vector with magnitude (or amplitude) A and phase angle θ, is called angle notation.
In the context of periodic phenomena, such as a wave, phase angle is synonymous with phase.
for a vector with magnitude (or amplitude) A and phase angle θ, is called angle notation.
