CHAPTER 07
COORDINATE GEOMETRY

Distance Formula
Section Formula
Area of a Triangle
Distance Formula: The length of a line segment joining A and B is the distance
between two points $A({x_1}, {y_1})$ and $({x_2},{y_2})$ is $\sqrt {(x_2 - x_1)^2 + (y_2 - y_1)^2}$
The distance of a point $\left( {x,y} \right)$ from the origin is $\sqrt {({x^2} + {y^2})}$ . The distance of P from x-axis is y units and from y-axis is x-units.
Section Formula: The co-ordinates of the points p(x, y) which divides the line segment joining the points $A({x_1}, {y_1})$ and $B({x_{2\;,\;}}{y_2})$ in the ratio ${m_{1\;}}:\;{m_2}$ are $\left( {{{{m_1}{x_2} + {m_2}{x_1}} \over {{m_1} + {m_2}}},{{{m_1}{y_2} + {m_2}{y_1}} \over {{m_1} + {m_2}}}} \right)$ we can take ratio as $k\;:\;1,\;\;k = \frac{{{m_1}}}{{{m_2}}}$
Mid-point Formula: The mid-points of the line segment joining the points $P({x_1},{y_2})\;\;\;and\;\;\;Q({x_2},{y_2})$ is $\left( {\frac{{{x_1} + {x_2}}}{2},\frac{{{y_1} + {y_2}}}{2}} \right)$
Area of a Triangle: The area of the triangle formed by the points $({x_1},{y_1}),\;({x_2},{y_2})\;and\;({x_3},{y_3})$ is the numeric value of the expressions ${1 \over 2}\left| {{x_1}\left( {{y_2} - {y_3}} \right) + {x_2}\left( {{y_3} - {y_1}} \right) + {x_3}\left( {{y_1} - {y_2}} \right)} \right|$ .
If three points are collinear then we cannot draw a triangle, so the area will be zero i.e. $|{x_1}({y_2} - {y_3}) + {x_2}({y_3} - {y_1}) + {x_3}({y_1} - {y_2})| = 0$
