Choose the false statement :

Options

A. Line `oversetharr(AB)` is the same as line `oversetharr(BA)`
B. Ray `vec(AB)` is the same as ray `vec(BA)`
C. Line segment `bar(AB)` is the same as the line segment `bar(BA)`
D. None of these

Answer

To solve the question "Choose the false statement," we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understand the Definitions:**
- **Line:** A straight path that extends indefinitely in both directions with no endpoints.
- **Ray:** A part of a line that starts at a fixed point and extends indefinitely in one direction.
- **Line Segment:** A part of a line that has two endpoints and a finite length.

2. **Evaluate Each Option:**
- **Option 1:** "If line A is B, line A is B and line B is A, is it the same?"
- This statement is true. Lines are defined by their properties and are equal if they have the same points.

- **Option 2:** "A ray has a fixed starting point but an ending point."
- This statement is false. A ray has a fixed starting point but extends indefinitely in one direction, meaning it does not have an ending point.

- **Option 3:** "Line segment A and B is a part of a line that has two endpoints."
- This statement is true. A line segment indeed has two endpoints and a finite length.

3. **Identify the False Statement:**
- Based on the evaluation, **Option 2** is the false statement because it incorrectly states that a ray has an ending point.

### Conclusion:
The false statement is **Option 2**.
