Opposite rays are rays that share the same endpoint (have a common endpoint), but they also form a line.
Not always.
A line
that one!
No, it is not possible to measure the length of a pair of opposite rays because opposite rays extend infinitely in opposite directions without endpoints. Since they have no defined length or endpoints to measure between, they cannot be quantified like line segments. Thus, their "length" is considered infinite in both directions.
To determine if segments Ef and fe form a line or are opposite rays, we need to know their orientation and endpoints. If points E, f, and F are collinear and lie on the same straight line, then Ef and fe could represent opposite rays, extending in opposite directions from point f. However, if they do not share a common endpoint or are not collinear, they do not form a line or opposite rays.

Start in the same point but are going in opposite directions

Yes. They diverge from a common endpoint in opposite directions.
They have one point in common.

maybe
