The major difference between angle modulation and amplitude
modulation is the variation of amplitude,frequency and phase.

As in amplitude modulation the amplitude of the carrier
varies in accordance to the modulating signal but in case of
angle modulation the frequency and phase of the carrier
signal varies in accordance to modulating signal but the
amplitude of carrier remains same.
for further clarifications we can refer their (angle
modulation and amplitude modulation)output waveforms.
