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
Line BA
we all know, a line segment is a portion of line with two fixed points A and B , but this segment has no specific direction i. e AB and BA are both line segments but if we give direction to this line segment suppose from A to B, then it becomes directed line segment, which is also called as vector AB having direction from A to B.so, a line segment with specific direction is called directed(having direction) line segment.
If these are vectors, then ba = - ab
No. A half line (also called a ray) is a linear object which starts at the first point, and extends to infinity through the second point. So the half-line (or ray) AB starts at point A, and shoots 'through' B and continues past B to infinity. The half-line BA is the other way around: it starts at point B, and then shoots 'through' A and continues past A to infinity. These two half-lines/rays end up extending to infinity in opposite directions, so they are not the same (not congruent).

yes it is

Yes.
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.
Two distinct points determine exactly one line. That line is the shortest path between the two points. ... Two points also determine a ray, a segment, and a distance, symbolized for points A and B by AB (or BA when B is the endpoint), AB, and AB respectively.
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
Yes, but then again it depends on what or where they are!
If these are vectors, then ba = - ab
Yes, provided it is the ray. If AB is a vector then the answer is no.
