Yes.
yes
Yes, provided it is the ray. If AB is a vector then the answer is no.
Yes, straight line AB is the same as straight line BA. Both represent the same geometric line segment connecting points A and B, regardless of the order of the points. The direction does not change the line itself; thus, AB and BA are equivalent.
[(aa + bb) + (ab+ba)(aa+bb)*(ab+ba)]*[a + (ab+ba)(aa+bb)*b]
no; commutative
yes
If these are vectors, then ba = - ab
Yes, provided it is the ray. If AB is a vector then the answer is no.
The GCF is ab
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.
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
[(aa + bb) + (ab+ba)(aa+bb)*(ab+ba)]*[a + (ab+ba)(aa+bb)*b]
NB, Nb
Line BA
Yes, It doesn't madder what direction you name them unless you were given specific instructions.
I think its BA.
AB and BA.
