A pair of adjacent angles whose non-common sides are opposite rays are called a linear pair. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Linear pair
Opposite Rays - are collinear rays having the same endpoint.
The angle that is formed by the opposite rays is called the straight angle. This is from the fact that the opposite rays form a straight line.
opposite rays have common end points
.
AB and BA.

Not clear what exactly the question is.
If I understand the question: Either pair of opposite angles formed by the intersection of 2 lines.
Fin rays are bony structures found in the fins of fish and other aquatic animals. They provide support and help in the movement and stability of the fins. The number and structure of fin rays can vary among different species.
Because we can't see the image you're referring to, we can't give the answer to which ray is opposite to BA. However, we can help. Opposite rays are two rays that both start from a common point and go off in exactly opposite directions. So, if there are two rays (BA and BC) with a common endpoint (B) going in different directions, they are called opposite rays.
