Key Topics to Revise

1

1. Basic Coordinate Terms

  • The x-coordinate of a point is called the abscissa.
  • The y-coordinate of a point is called the ordinate.
  • The abscissa is the distance of a point from the y-axis.
2

2. Distance Formula

  • Distance between two points on the x-axis is found by subtracting their x-values.
  • Distance between two points on the y-axis is found by subtracting their y-values.
  • The distance formula for two general points is derived using the Pythagoras theorem.
3

3. Applications of Distance Formula

  • If the sum of any two sides of three points is greater than the third, the points form a triangle.
  • For points (3, 2), (-2, -3), and (2, 3), the distances are PQ = √50, QR = √52, and PR = √2.
  • These points form a right triangle because PQ² + PR² = QR².
4

4. Equidistant Points and Locus Idea

  • A point equidistant from two given points lies on the perpendicular bisector of the segment joining them.
  • For points (7, 1) and (3, 5), the relation between x and y for an equidistant point is x - y = 2.
  • A point on the y-axis has the form (0, y).
