Can the length of a ray be measurred ?

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding a Ray**: A ray is defined as a part of a line that has a fixed starting point (called the endpoint) and extends infinitely in one direction. 2. **Identifying Fixed Points**: To measure the length of any line segment, we need two fixed points: a starting point and an endpoint. The length is determined by the distance between these two points. 3. **Analyzing the Ray**: In the case of a ray, we have one fixed point (the starting point), but we do not have a defined endpoint. The ray continues indefinitely in one direction without terminating. 4. **Conclusion**: Since we cannot identify a second fixed point (the endpoint) for the ray, we cannot measure its length. Therefore, the length of a ray cannot be measured. 5. **Final Answer**: No, the length of a ray cannot be measured. ---
