Answer :
To solve the question, we need to determine the correct term used to describe points that lie on the same line.
### Step-by-Step Solution:
1. Understand the Definitions:
- Complementary: In geometry, this term typically refers to two angles whose measures add up to 90 degrees. This term is related to angles, not points on a line.
- Collinear: This term is used when points lie on the same straight line. This fits the context given in the question.
- Segments: A segment is a part of a line that is bounded by two distinct end points. This does not describe points lying on the same line but rather a part of the line itself.
- Rays: A ray is a line with a single end point that extends infinitely in one direction. This term is concerned with the direction and length characteristics of a line, not the positioning of points.
2. Match the Definition to the Given Context:
The question is asking for the term that describes the scenario where two or more points lie on the same line. Based on the definitions provided:
- The term collinear directly fits this description, as collinear points are exactly those that lie on the same line.
3. Conclude the Correct Answer:
Therefore, the term that correctly completes the sentence is "collinear."
So, the correct choice is:
B. collinear
### Answer:
Two or more points are collinear if they lie on the same line.
