Is a LH Inswing door identical to a RH Outswing door, just turned

Inswing and outswing only apply to exterior doors that have a threshold.
If it is an interior door, it matters not whether it is inswing or
outswing. You order a LH or a RH and put it in the way that you want.

On the exterior door, the threshold is configured for inswing or
outswing. They should not be reversed. And no, they are not just the
same door turned around. The thresholds and the glass (if it has glass)
will be different.

Stand in the doorway with the door open. Put your back to the hinges.
If the door is on your right, it is a RH. If the door is on your left,
it is a LH.


A prehung interior door is not symmetrical font to back as it is set in the
jams already. It is prehung 'flush' with one side of the jam surround.
