8 collinear points determine 28 unique line segments
If each segment intersects exactly two other segment but could, if extended, intersect the third, then the figure is a quadrilateral. Otherwise it is a parallelogram.
Opposite Rays - are collinear rays having the same endpoint.
It is an angle.
a triangle
Oppsite rays
Opposite Rays
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.
no
Opposite Rays
One! That is what collinear means!

They are rays that lie on the same line. For example draw a horizontal line. Now put 3 points anywhere on that line. Next draw 3 rays, some going to the left, some going to the right. These rays are collinear.
It is an angle.
