Question

UpStudy AI · Accepted Answer

The correct options that are **one-dimensional** and have **infinite length** are:

- **A. Line**
- **E. Ray**

**Explanation:**

1. **A. Line**
   - **Dimension:** One-dimensional
   - **Length:** Extends infinitely in both directions
   - **Conclusion:** **✔️** It meets both criteria.

2. **B. Plane**
   - **Dimension:** Two-dimensional
   - **Conclusion:** ❌ It does not meet the one-dimensional requirement.

3. **C. Angle**
   - **Dimension:** Typically considered in two-dimensional geometry as it involves two rays.
   - **Conclusion:** ❌ It is not one-dimensional.

4. **D. Segment**
   - **Dimension:** One-dimensional
   - **Length:** Finite
   - **Conclusion:** ❌ It does not have infinite length.

5. **E. Ray**
   - **Dimension:** One-dimensional
   - **Length:** Extends infinitely in one direction
   - **Conclusion:** **✔️** It is one-dimensional and has infinite length in one direction.

6. **F. Point**
   - **Dimension:** Zero-dimensional
   - **Conclusion:** ❌ It does not meet either requirement.

**Final Answer:**  
**A. Line** and **E. Ray**
**A. Line** and **E. Ray** are one-dimensional and have infinite length.

Which of the following are one-dimensional and have infinite length? Check all that apply. \( \square \) A. Line \( \square \) B. Plane \( \square \) C. Angle \( \square \) D. Segment \( \square \) E. Ray \( \square \) F. Point
