A vertex.
-- Two rays with a common endpoint form an angle. -- If they have a common endpoint, then they are collinear. So I guess, technically, the conditions described in the question aren't possible.
Perpendicular rays are two rays that intersect one another to form four right angles. Below is an image that shows two perpendicular rays.
Opposite Rays
no
Not only must they intersect, but they must be parts of the same line.
collinear means on the same line so they would be collinear if they are on the same line.!
Oppsite rays
Opposite Rays
parallellines
Not necessarily. If two rays are on different planes, but the planes intersect, it is possible that the rays would also intersect, but the plane intersection would have to happen where the rays are located.
A vertex.
It's an angle.

What about them?These are known as opposite rays. They form a line.
