COARDINATE GEOMETERY

COARDINATE GEOMETERY

1. BASIC DEFINITIONS

   • COARDINATE AXES:- X-AXIS AND Y-AXIS ARE TOGETHER CALLED COARDINATE AXES.
     • CARTESIAN PLANE:-THE PLANE ON WHICH THE X-AXIS AND THE Y-AXIS ARE PRESENT.
       • ORIGIN:- THE POINT OF INTERSECTION OF X-AXIS AND Y-AXIS.
         • ABISSICA:- THE DISTANCE OF A POINT FROM X-AXIS TO THE Y-AXIS.
           • ORDINATE:- THE DISTANCE OF A POINT FROM Y-AXIS TO X-AXIS

2. THE DISTANCE BETWEEN TWO POINTS (X1,Y1) AND (X2,Y2)IS GIVEN BY d(P, Q) = √ (x2 − x1)^2 + (y2 − y1)^2
