Chapter 1: Q5 (page 14)

For the following figure, find $\overset{\leftrightarrow}{A B}$ is the same as $\overset{\leftrightarrow}{B A}$ or not.

Short Answer

Expert verified

Yes, $\overset{\leftrightarrow}{A B}$ is the same as $\overset{\leftrightarrow}{B A}$ .

Step by step solution

Step 1. Check the figure.

Consider the figure.

Step 2. Apply the concept of the line.

A line goes infinitely in both directions. It is represented by a two-headed arrow. A line can be represented by taking any two points.

Here, a line $\overset{\leftrightarrow}{A B}$ has two points A and B on it, and similarly, the line $\overset{\leftrightarrow}{B A}$ has two points A and B on it.

Step 3. Relation between AB and BA.

Thus, the line can be represented in both ways, $\overset{\leftrightarrow}{A B}$ or $\overset{\leftrightarrow}{B A}$ as the order of the points is not considered while naming a line.

Therefore, $\overset{\leftrightarrow}{A B}$ is the same $\overset{\leftrightarrow}{B A}$ , because both represent the same line.
