Key Topics to Revise

1

Distance Between Two Points

  • Distance between points on X-axis: |x₂ - x₁|
  • Distance between points on Y-axis: |y₂ - y₁|
  • Distance from origin to point P(x,y) is √(x² + y²)
2

Section Formula

  • Section formula finds coordinates of point dividing line segment in given ratio
  • Internal division: point lies between the two given points
  • Midpoint is special case when ratio is 1:1
3

Centroid of a Triangle

  • Centroid is point of concurrency of medians
  • Divides each median in ratio 2:1
  • Always lies inside the triangle
4

Area of Triangle

  • Area can be calculated using coordinates of vertices
  • Formula gives area in terms of coordinates only
  • Always take absolute value to ensure positive area
