Topics in Co-Ordinate Geometry
1
Introduction to Coordinate System
- We need exactly two references to locate a point uniquely in a plane
- A coordinate system uses two perpendicular number lines intersecting at origin
- The horizontal line is called X-axis and vertical line is called Y-axis
2
Cartesian Plane and Quadrants
- The coordinate plane is divided into four regions called quadrants
- Quadrants are numbered I, II, III, IV in anticlockwise direction starting from top-right
- Each quadrant has specific sign patterns for coordinates
3
Plotting Points - Step-by-Step Method
- Start from origin (0,0) for every point
- Move horizontally first (x-coordinate), then vertically (y-coordinate)
- Positive x means move right, negative x means move left
4
Special Points and Lines
- Points on X-axis have y-coordinate = 0, written as (x, 0)
- Points on Y-axis have x-coordinate = 0, written as (0, y)
- Origin has both coordinates = 0, written as (0, 0)
