The notation for a vector with magnitude (or amplitude) A and phase angle θ, is called angle notation. This notation is frequently used to represent an electrical impedance. In this case the phase angle is the phase difference between the voltage applied to the impedance and the current driven through it.
In the context of periodic phenomena, such as a wave, phase angle is synonymous with phase.
