Question

Anita says ray SR can also be called ray RS. Do you agree? Explain.

Answer 1

Assuming that S is the end point.

No, I do not agree because you have to start with the endpoint.

Answer 2

In ray SR, S is the initial point and R is the terminal point.

In ray RS, these points are swapped. That is, the initial point is R while the terminal point is S.

So, ray RS is oppositely oriented to SR.

Hence, ray SR should not be called ray RS.
