Answer to the question:

A quick way of ensuring a more precise method of rotation; Hold down the SHIFT key whilst you rotate the object using the 'green' rotate handle, this will ensure that it rotates in 15 degree clicks.
If however you want to be even more precise in your rotation, then you should use the Format Picture dialog box; (Select the Graphic, Right click and from the shortcut menu choose Format Picture).
