Key Points: Combined Equation of a Pair Lines
| General Equation | Combined equation of a pair of lines through the origin | Combined equation of a pair of lines not passing through the origin |
|---|---|---|
| ax² + 2hxy + by² = 0 | ax² + 2hxy + by² + 2gx + 2fy + c = 0 | |
| Necessary Conditions for Real Lines | h² − ab ≥ 0 | \[\begin{vmatrix} \mathrm{a} & \mathrm{h} & \mathrm{g} \\ \mathrm{h} & \mathrm{b} & \mathrm{f} \\ \mathrm{g} & \mathrm{f} & \mathrm{c} \end{vmatrix}=0,\] h² − ab ≥ 0 |
| Point of intersection | (0, 0) | \[\left(\frac{\mathrm{hf-bg}}{\mathrm{ab-h^2}},\frac{\mathrm{gh-af}}{\mathrm{ab-h^2}}\right)\] |
| Angle between the lines | \[\tan\theta=\left|\frac{2\sqrt{\mathrm{h}^2-\mathrm{ab}}}{\mathrm{a}+\mathrm{b}}\right|\] | \[\tan\theta=\left|\frac{2\sqrt{\mathrm{h}^{2}-\mathrm{ab}}}{\mathrm{a}+\mathrm{b}}\right|\] |
| For parallel (coincident) lines | h² − ab = 0 | h² − ab = 0, bg² = af², \[\frac{\mathrm{a}}{\mathrm{h}}=\frac{\mathrm{h}}{\mathrm{b}}=\frac{\mathrm{g}}{\mathrm{f}}\] |
| For perpendicular lines | a + b = 0 | a + b = 0 |
