How to align one side to the second

I want to align the short side to the longer one (picture). First, I tried to create a new transform orientation and then press s+z+0. But then, the long face also transformed a little bit.
The long side shall be the same orientation. Only the short (marked) side should adapt to the alignment of the long.

The red arrow shows the direction of the long side, this direction should get the short side too.

If i understand you right, you can use 2 ways:

  1. you can use face orientation (select a face and add orientation), but that work in this case only for 2 axes.
  2. use a helper object, extrude the desired face from a copy and snap to it

face_normal or snap to helper object.blend (661.8 KB)
