Pair of Straight Lines
- Homogeneous Equation
- Angle between the line pair represented by $ax^2+2hxy+by^2=0$
- Bisectors of the Angles between the Line Pair $ax^2+2hxy+by^2=0$
- Condition that the General Equation of Second Degree may Represent a Line Pair
- If the equations $ax^2+2hxy+by^2+2gx+2fy+c=0$ represent a a line pair, then $ax^2+2hxy+by^2=0$ represent a line pair through the origin parallel to the above pair.
