A. Line & Plane
B. Plane & Line segment
C. Point & Line segment
D. Point & Line
Answer:
The pair of undefined terms is used to define a ray is D. Point & Line
A ray is a part of a line that starts at a specific point (known as the endpoint) and extends infinitely in one direction. Therefore, a ray is defined by a point and a line, where the point represents the endpoint of the ray, and the line represents the direction in which the ray extends.
The other options listed do not include the necessary components to define a ray. A line is a set of points that extends infinitely in both directions, but it does not specify an endpoint for the ray. A plane is a flat surface that extends infinitely in all directions, and a line segment is a part of a line that has two endpoints, but neither of these terms can be used to define a ray.
