If the angle between the lines given by `ax^(2)+2hxy+by^(2)=0` is equal to the angle between lines given by `2x^(2)-5xy+3y^(2)=0`, then

If the angle between the lines represented by ax^(2) + 2hxy + by^(2) = 0 is equal to the angle between the lines 2x^(2) - 5xy + 3y^(2) = 0 , then show that 100(h^(2)-ab) = (a+b)^(2) .

The acute angle between the lines given by x^(2)+2(cottheta)xy+y^(2)=0 is

If the angle between the lines ax^(2)+xy+by^(2)=0 is 45^(@) , then

If the acute angle between the lines ax^(2)+2hxy+by^(2)=0 is congruent to the acute angle between the lines 3x^(2)-7xy+4y^(2)=0 , then

The acute angle between the lines given by x^(2)+2(cosectheta)xy+y^(2)=0 is

The angle between the lines ay^2-(1+lambda^2)xy-ax^2=0 is same as the angle between the line:

The angle between the lines ay^2-(1+lambda^2)xy-ax^2=0 is same as the angle between the line:

The angle between the lines x^(2) + 4xy + y^(2) = 0 is

If one of the lines given by ax^(2)+2hxy+by^(2)=0 is 4x-5y=0 then
