Represent `sqrt2, sqrt3 and sqrt5` on the real line

Explanation

To represent \( \sqrt{2} \), \( \sqrt{3} \), and \( \sqrt{5} \) on the real line, we can follow these steps:

### Step 1: Draw the Number Line
- Begin by drawing a horizontal line. Label a point on the left as \( 0 \) and a point to the right as \( 1 \).

### Step 2: Construct \( \sqrt{2} \)
1. **Create a Right Triangle**:
- From point \( O \) (which represents \( 0 \)), draw a vertical line segment of length \( 1 \) (this represents the unit length).
