Organize segments segment by plane

Hi there,
It might be easy but I’m probably missing somethin:
I have those segments in this triangular tower.
I just wanted to structure the data tree in 3 branches, one for each side of the tower.
but I’m still not find how to sort segment by his plane.
Planar tools seems doesn’t work precisely .
Any idea?

Thanks a lots
Nico
