Key Topics to Revise

1

Distance Formula

  • Distance between two points uses the Pythagoras theorem in coordinate plane
  • Formula works for points in any quadrant of the coordinate plane
  • Distance is always positive (we take only positive square root)
2

Section Formula

  • Section formula finds coordinates of point dividing a line segment in given ratio
  • Ratio m₁:m₂ means the point divides segment into parts of lengths in ratio m₁:m₂
  • Internal division means point lies between the two given points
3

Problem-Solving Strategies

  • Step 1: Identify what is given and what needs to be found
  • Step 2: Choose appropriate formula (distance or section)
  • Step 3: Substitute values carefully, paying attention to signs
