I don't understand why Rotate[] and Translate[] behave differently. For example, ga and gb below look as I expected:

ga = Graphics[Line[{{0, 0}, {1, 0}}]];
gb = Rotate[ga, \[Pi]/4, {0, 0}];
gc = Translate[gb, {1, 1}];

But gc results in this: enter image description here

Your problem here is that you are calling Graphics too early. You want to Rotate and Translate the Line, not the Graphics.

ga = Line[{{0, 0}, {1, 0}}];
gb = Rotate[ga, \[Pi]/4, {0, 0}];
gc = Translate[gb, {1, 1}];

Will do what you want.

Graphics[{Red, ga, Blue, gb, Green, gc}]

  • $\begingroup$ @JosephO'Rourke just to add to this: for some reason WRI decided that Rotate should also be able to rotate arbitrary stuff displayed on the screen outside of a Graphics call, which is why your gb seemed to work. $\endgroup$
