Key Topics to Revise

1

Basic Concepts and Coordinate System

  • Coordinate axes consist of perpendicular x-axis (horizontal) and y-axis (vertical)
  • Any point P has coordinates (x, y) where x is the distance from y-axis and y is the distance from x-axis
  • Points on x-axis have form (x, 0) and points on y-axis have form (0, y)
2

Distance Formula

  • Distance between two points can be found using Pythagoras theorem
  • For points on same axis, distance is simply the difference of coordinates
  • Distance formula works for points in any quadrants
3

Section Formula (Internal Division)

  • Section formula finds coordinates of a point dividing a line segment in a given ratio
  • Internal division means the point lies between the two given points
  • The formula is derived using similar triangles and proportional segments
4

Special Applications and Problem Types

  • Finding if three points are collinear using distance formula
  • Determining types of triangles and quadrilaterals using distance formula
  • Finding points on axes equidistant from given points
