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.
