I defined phase as in single, 2 or 3. You just chose to ignore it.

You gave a definition that is historical, not from an engineering
perspective and you didn't define anything more than 3. You would
think if it's so simple, someone could define it for N phases.
And then you refuse to answer the obvious questions
that even a student would ask a teacher. According to you, two
phase was 90 deg over four wires. OK, so, if it was over 3 wires, using
one shared neutral, would two phases still be present? Now I change
the phase to 179 degrees or 181 degrees, are there still two phases?
Yes? No?

Why then are there not two phases present when it;s 180? The answer
of course is that there still are two phases, it just becomes a less
interesting case.

You look at a system from end to end, not any small segment.
This is a single phase system.

Inability to answer the simple relevant questions a student would
ask a teacher noted.

I answered the question several times. I just told you what
electricians and inspectors call the service you have in your house.
If you can't understand that and need some other rationalizations to
explain what you have, go for it.
I don't care anymore.
