Conditional Statement: "If two lines are parallel then the two lines are in the same plane."

"If two lines are not parallel then the two lines are not in the same plane" is the conditional statement's What

The statement, **"If two lines are not parallel then the two lines are not in the same plane,"** is the **inverse** of the original conditional statement.

To break it down:

1. **Original statement (conditional):**  
   "If two lines are parallel, then they are in the same plane."

   This is of the form **if p, then q**, where:
   - **p:** "Two lines are parallel."
   - **q:** "The two lines are in the same plane."

2. **Inverse statement:**  
   The inverse of a conditional statement is formed by negating both the hypothesis (p) and the conclusion (q).  
   The inverse of "If p, then q" is "If not p, then not q."

   - Original: "If two lines are parallel, then they are in the same plane."
   - **Inverse:** "If two lines are not parallel, then they are not in the same plane."

This inverse statement is not necessarily true, as two lines can be non-parallel yet still in the same plane (e.g., intersecting lines).

2. What is the contrapositive of the original statement?
3. Can two lines be in the same plane and not be parallel?
4. How do skew lines relate to the concept of lines not being in the same plane?
5. Can you think of an example of non-parallel lines that are in the same plane?

**Tip:** The truth value of the inverse statement is not guaranteed to match that of the original conditional.
