What is the name of the ray opposite op

To find the name of the ray opposite to "op," we first need to understand what a ray is. A ray is a part of a line with one endpoint and extends indefinitely in one direction.

If "op" is a ray, it has an endpoint at point "o." To find the ray opposite to it, we need to extend the ray in the opposite direction.

However, without additional information about the specific line or geometric figure we are dealing with, it is not possible to determine the name of the ray opposite to "op". Please provide more context or specific instructions related to the figure or line in question, so I can assist you further.
