yes
Yes, provided it is the ray. If AB is a vector then the answer is no.
naming a line is different from naming a ray. say for example ,if we have line AB,this is similar to line BA while ray AB is different from ray BA.
Yes.
True when the rays represent vectors. Not always true otherwise. This is partly because with vectors ab is not the same as ba whereas with ordinary lines such a distinction is not important. False

Yes.
Yes it names the same ray. For example in a square ABCD you can also call it DCBA or BCDA etc.
The ray opposite from ray BA is ray AB. These rays form a straight line.
naming a line is different from naming a ray. say for example ,if we have line AB,this is similar to line BA while ray AB is different from ray BA.
Ab and Ba are the same line because there are no endpoints to a line. Therefore, you can reverse the order of the letters. So, Cd and Dc are not the same ray because the first letter is the endpoint. So on ray Cd, point C is the endpoint and d is a point on the line coming from the endpoint. On ray Dc, D is the endpoint.
Yes, It doesn't madder what direction you name them unless you were given specific instructions.
Yes.
yes it is
If these are vectors, then ba = - ab
The GCF is ab
