Equation for pair of lines is
above expression is simplified as follows
x[ y - x cot(2α) ] = 0
From above expression , we get two equations that represent pair of lines
x= 0 ...................................(1)
y = x cot2α ..............................(2)
Equation (1) is y-axis . If two lines are perpendicular to each other , then other line is x-axis .
Since equation of x-axis is y = 0 , then we get cot2α = 0 or α = π/4
