Fill in the blanks :
A ray has no ____ length .

Answer

**Step-by-Step Solution:**

1. **Understanding the Concept of a Ray**: A ray is a part of a line that starts at a point and extends infinitely in one direction. This means that it does not have a fixed endpoint on one side.

2. **Identifying the Characteristics of a Ray**: Since a ray extends infinitely, it does not have a specific measurement of length. The length can be considered as always increasing as you can keep extending it further.

3. **Filling in the Blank**: Based on the understanding that a ray does not have a fixed length, we can fill in the blank. The correct statement is: "A ray has no **definite** length."

4. **Final Statement**: Therefore, the complete sentence is: "A ray has no definite length."
