no 2 points form a line, 3 points form a plane
A ray
Coplanar rays are rays that lie within the same plane. In geometry, a ray is defined as a part of a line that has a fixed starting point and extends infinitely in one direction. When multiple rays are coplanar, they can be used to form angles or shapes within that plane, and their relationships can be analyzed in terms of intersection, parallelism, or other geometric properties.
Line, Ray and segment
Plane.
If on your paper your answers are point, ray, line segment, or plane i think it will be Plane
The vertex is the intersection of the rays that form an angle. The other ends go on indefinitely.
Presumably, the "three dimensional triangular plane" is actually a two dimensional plane which is "tilted" with respect to the axes. The point of intersection is simply the coordinates of the solution to the simultaneous equations for the line and the plane.
A ray
A line or a ray - depending on whether the planes are finite or infinite.

Not in plane Euclidean geometry.
A ray does not separate a plane. In geometry, a ray is defined as a part of a line that starts at a point and extends infinitely in one direction. While a ray can divide a plane into two regions, it does not create a distinct separation like a line does, as it does not extend infinitely in both directions. Thus, the concept of separation is not applicable to a single ray in a plane.
A ray is not an undefined term.
Line, Ray and segment
line
Plane.
A right angle.
