Line BA
AB and BA.
Yes.
According to the symmetric property (and common sense) line segmetn AB is congruet to line segment BA since they are the same segment, just with a different name
Yes, It doesn't madder what direction you name them unless you were given specific instructions.
The GCF is ab
[(aa + bb) + (ab+ba)(aa+bb)*(ab+ba)]*[a + (ab+ba)(aa+bb)*b]
Yes.
NB, Nb
Line BA
Yes, provided it is the ray. If AB is a vector then the answer is no.
AB and BA.
I think its BA.
Honey, lines AB and BA are like two peas in a pod - they're the same darn thing! In geometry, the order of the points on a line doesn't matter, so whether you call it line AB or line BA, it's all just one straight shot from point A to point B. So, yes, line AB is indeed the same as line BA.
Yes.

no; commutative
