the notation RY(-->) and YR(-->) represent the same ray

true or false

3 answers

False.
why?
This is false because the notation RY(-->) means that the ray starts at point R and extends in the direction of point Y, while the notation YR(-->) means that the ray starts at point Y and extends in the direction of point R. These are different rays with different starting points and directions. The order of the points in the notation is important and changes the meaning of the ray.
