Final answer:
Rays ba and bc are not the same because ray ba extends infinitely from b towards a, while ray bc extends infinitely from b towards c, making them opposite rays.
Step-by-step explanation:
Assuming you have a line with points a, b, and c on the line in the order listed, rays ba and bc are not the same rays. A ray is named starting with its endpoint and extending infinitely in the direction of the second point listed. Thus, ray ba starts at point b and extends infinitely towards point a, while ray bc starts at point b and extends infinitely towards point c. In this example, the rays are opposite to each other because they extend in different directions along the same line.
