Coordinate Geometry

Coordinate Geometry

1. Propounded by: Rene Descartes

2. Definition: System of locating a point on a plane with the help of two axes- x axis or abscissa and y axis or ordinate

   • The two axes are actually two lines perpendicular to each other
     • The point at which the two lines or axes intersect is called oigin
       • The coordinates of origin is (0,0)
   • The cartesian system consists of 4 parts formed by the intersection of the two axes. these 4 parts are called quadrants
     • the coordinates of a point are of the form (+,+) in the first quadrant, (-,+) in the second quadrant, (-,-) in the third quadrant and (+,-) in the fourth quadrant, where + denotes a positive real number and - denotes a negative real number.

3. Cartesian System (named in Descartes' honour)
