Yet another method:

Under the Modify menu item in the upper toolbar there is a Move and Rotate item. I chose that, whereupon I was prompted to select, which I accomplished by clicking in sequence on each of my nineteen entities and then hitting the Enter button, whereupon my drawing started to spin. I was saved by a popup menu which gave me the opportunity to select the rotation angle (180), but I am stymied by an inability to specify a good reference point, and worse, no useful rotation axis, so my rotated group of nineteen entities overlaps the original group, and I cannot move it from there.

The good  news is that there is indeed a displacement between the two groups.
