There are many ways depending on what your PC operating system is and what software you have. Here’s one way assuming you are using Windows.
Using the snapshot tool in Adobe reader take a snapshot of the layout. Paste this snapshot into the Windows Paint accessory. Under Image; Rotate; select Flip Horizontally. You may have to use the resize to adjust it to the right size.
