Phase Angle control

[Hon]

Anyone know what it means?

From the para below, does that means Phase Angle Control will control Hz and hence reducing Voltage?

"Phase Angle control uses a low frequecy switch to chop an AC sine wave. The firing angle of the switch is varied. The average voltage will be proportional the area under the sine wave. Thus, the average voltage is the integral from the firing angle to the zero crossing, the cosine of the firing angle."
