Constant phase difference means every wave has and maintains its original phase angle throughout the course of their interactions
That's a condition for coherence
So one wave could have a difference of 180 degrees, another 10 degrees and another 123 degrees, but as as long as it’s constant throughout, its coherent?

Yes exactly so.
In the mark scheme, if you dare say coherent waves must have equal phase angles, it's an automatic fail. one could even get arrested for that. hehehehe
