You are the right place to get all information about Coordinate Geometry Class 9 maths chapters 3. Coordinate Geometry formulas play a vital role in preparing you for the class 9 exam as well as higher studies. Coordinate Geometry formulas are very helpful for better scores in the exam.  Check Coordinate Geometry formulas according to class 9:

\[ Equation\; of\; a \;line = ax + by + c = 0 \]
\[ Equation\; of\; a \;circle = x^2 + y^2 = r^2 \]
Here ‘\(r \)’ is the radius of the circle
\[ Equation\; of \;a \;parabola = y^2 = 4ax \]
\[ Equation\; of \;an\; ellipse = \frac{{x^2 }}{{a^2 }} + \frac{{y^2 }}{{b^2 }} = 1 \]
\[ Equation\; of\; hyperbola = \frac{{x^2 }}{{a^2 }} – \frac{{y^2 }}{{b^2 }} = 1 \]
\[ Distance\; formula\; D = \sqrt {\begin{bmatrix}{\left( {x_2 – x_1 } \right)^2 } +\\ {\left( {y_2 – y_1 } \right)^2 }\end{bmatrix}} \]
\[ Angle \;between\; two\; lines\; \theta = \tan ^{ – 1} \left( {\frac{{m_2 – m_1 }}{{1 + m_1 m_2 }}} \right) \]
