Having trouble rotating rectangle shape

I'm trying to use the rotate function to rotate a rectangle object and display it. I can create the rectangle, and no errors are called when using the rotate function on the handle to the rectangle object, but I cannot figure out how to then display that rotated rectangle to the screen. Also I'm not sure if the handle to the original rectangle would retain that rotation in it. By the way, I know I could solve this in a lot of other ways, like by using patch or fill and using a rotation matrix to transform the coordinates, but that's not really the goal. I just want to know how to use the rotate function in a useful way.

figure(1)
axis('equal')
r = rectangle('position',[1 1 1 2]);

rotate(r, [0 0 1], 30);
refreshdata
drawnow

Input argument of rotate function shall be a surface, patch, line, text, or image object. How about the following?

figure
axis('equal')
h = patch('XData',[1 2 2 1],'YData',[1 1 3 3],'FaceColor','none');
view(3)
rotate(h, [0 0 1], 30)
grid on

Thanks! I didn't realize that there wasn't a rectangle object, but this makes sense now.
