Sagot :

Answer:If \( \mathbb{R}^3 \) refers to the three-dimensional Euclidean space, the relationships between lines can be described as follows:

1. **Two lines that do not intersect**:

  - They can either be parallel or skew.

2. **Two lines lying in the same plane**:

  - They can either intersect or be parallel.

3. **Two lines not lying in the same plane**:

  - They are skew.

4. **Two lines that are parallel**:

  - They lie in the same plane and do not intersect.

5. **Two lines that are perpendicular**:

  - They intersect and form a right angle.

6. **Two lines that are skew**:

  - They do not intersect and do not lie in the same plane.

Based on this, the correctness of each statement can be assessed:

- A. and do not intersect: This can be true if the lines are either parallel or skew.

- B. and lie in the same plane: This can be true if the lines either intersect or are parallel.

- C. and do not lie in the same plane: This is true if the lines are skew.

- D. and are parallel: This implies the lines do not intersect and lie in the same plane.

- E. and are perpendicular: This implies the lines intersect at a right angle.

- F. and are skew: This implies the lines do not intersect and do not lie in the same plane.

Therefore:

- Statements A, B, C, and D can be true in certain contexts.

- Statement E is true if the lines intersect at a right angle.

- Statement F is true if the lines do not intersect and do not lie in the same plane.
