It is to label two points.Wrong answer! You need to draw a ray first, Here is the official Steps:Step one: Draw a Ray with endpoint CStep two: Use the Compass to measure the length of Point A and BStep three: Use the same compass setting, put the compass point on point C.Then draw an arc that intersects the ray. THEN Label the points of intersection D.
A line with a dot at one end and an arrow at the other end is called a ray in geometry. A ray has a starting point (the dot) and extends infinitely in one direction (towards the arrow). It is often denoted by naming the starting point and any other point on the ray, such as "ray AB" if A is the starting point and B is another point on the ray. Rays are commonly used in geometric constructions and proofs.
A Ray.
ray
Strictly speaking, a "ray" is in the family of lines and line segments. A line is defined as a one-dimensional object of infinite length with no well-defined endpoints (since "infinity" isn't a well-defined value). It's the 1-D analogue to a plane or a space. A line segment is the finite equivalent of a line. A ray is a bit stranger: it's infinite in length, but has one well-defined end-point, where the ray originates. They show up a lot in classical optics because if nothing interrupts it, a light ray is created at some point and then continues forever.
tangent
A tangent
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.
It is called a bisector.
Plane.
The point at which a ray of light or a line intersects or touches a surface is known as the point of incidence. This point is important in studying reflection and refraction of light.

A ray is not an undefined term.
