Unfortunately, differently from PowerPoint, Microsoft Word does not allow you to rotate or flip
text.
Even if you create a text box, rotate or flip it in PowerPoint and
paste it into Word as an “MS
Office Drawing Object”, it
comes into Word the right way up – thus proving that there's no such thing
as an MS Office Drawing Object; there are PowerPoint drawing objects, and
there are Word drawing objects.
However, there are a number of workarounds
for this. I have written this post to show you how you can get it done.
