Notes, solutions of unit 09, General Mathematics 9, for Punjab Curriculum & Textbook Board (PCTB), Lahore.

• Define coordinate geometry.
• Derive distance formula to calculate distance between two points given in Cartesian plane.
• Use distance formula to find distance between two given points.
• Define collinear points. Distinguish between collinear and non-collinear points.
• Use distance formula to show that given three (or more) points are collinear.
• Use distance formula to show that the given three non-collinear points form
  • an equilateral triangle,
  • an isosceles triangle,
  • a right angled triangle,
  • a scalene triangle.
• Use distance formula to show that given four non-collinear points form
  • a square,
  • a rectangle,
  • a parallelogram.
• Recognize the formula to find the midpoint of the line joining two given points.
• Apply distance and mid point formulae to solve/verify different standard results related to geometry.
