If one of the lines of the pair `a x^2+2h x y+b y^2=0` bisects the angle between the positive direction of the axes. Then find the relation for `a ,b` and `h`.

Explanation

To solve the problem, we need to find the relationship between \( a \), \( b \), and \( h \) given that one of the lines represented by the equation \( ax^2 + 2hxy + by^2 = 0 \) bisects the angle between the positive direction of the axes.

### Step-by-Step Solution:

1. **Understanding the Equation of the Pair of Lines**:
The equation \( ax^2 + 2hxy + by^2 = 0 \) represents a pair of straight lines through the origin. The lines can be expressed in the form \( y = m_1x \) and \( y = m_2x \), where \( m_1 \) and \( m_2 \) are the slopes of the lines.

2. **Identifying the Angle Bisector**:
