Rotate and Normal


I have been trying to use the new Rotate command.  It seems that when
you use it it leaves the result in an unevaluated form, but I need to
make futher calculations after performing the rotation. My
understanding is that this is what Normal is for. But when I try to
use it I do not get any change in the output.

An example:

In(1)= Rotate[Line[{{0, 0}, {1, 2}}], 30 =B0, {1, 1}]
Out(1)=Rotate[Disk[{2,2}],2],45 =B0,{3,1}]

In(2)= Rotate[Line[{{0, 0}, {1, 2}}], 30 =B0, {1, 1}]//Normal
Out(2)=Rotate[Disk[{2,2}],2],45 =B0,{3,1}]

What am I doing wrong. What must I do to get an output in a form I can
use for futher compuitations rather than just for display?

Thanks
Gary
