Is Ray AB the same as Ray BA?
yes
How is naming a ray similar or naming a 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.
Is the endpoint of a ray always the second of two letters used to name the ray?
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
Is AB the same as BA?
Yes.
Odd number of a's and even number of b's in regular expression automata?
[(aa + bb) + (ab+ba)(aa+bb)*(ab+ba)]*[a + (ab+ba)(aa+bb)*b]
Is Ray AB the same as Ray BA?
yes
Does Ray AB equal Ray BA?
Yes.
Is ray ab and ray ba name the same ray?
Yes it names the same ray. For example in a square ABCD you can also call it DCBA or BCDA etc.
Which ray is opposite from ba?
The ray opposite from ray BA is ray AB. These rays form a straight line.

Explain why Ab and Ba are the same line but Cd and Dc are not not the same ray?
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.
Does AB and BA name the same ray?
Yes, It doesn't madder what direction you name them unless you were given specific instructions.
Is AB the same as BA?
Yes.
Is line AB the same of line BA?
yes it is
If ab then ba?
If these are vectors, then ba = - ab
What is gcd of (ab)(ba)?
The GCF is ab
