Modify feature: moving or change the shape

Question

When the user makes some edit on features on ArcMap, the user can make some changes like moving the feature, editing the attributes or changing the shape.

How could I know if the user moved the feature or changed the shape?

I want to put different conditions on the editing according to what the user did.

Answer 1

Recalculate the centroid of the shape; compare it to the old one. This should almost always change due to a move or reshape.
