Topics in Section Formula

1

Section Formula for Internal Division

  • A point P divides the line segment joining two points A and B internally when P lies between A and B
  • The ratio m:n means that AP:PB = m:n, where AP and PB are the distances from A to P and P to B respectively
  • The section formula gives the exact coordinates of the dividing point when we know the coordinates of the endpoints and the ratio
2

Mid-Point Formula

  • The mid-point is a special case of section formula where the point divides the line segment in the ratio 1:1
  • Mid-point is equidistant from both endpoints of the line segment
  • The formula is obtained by substituting m=n=1 in the section formula
3

Centroid of a Triangle

  • The centroid is the point where all three medians of a triangle intersect
  • A median is a line segment joining a vertex to the mid-point of the opposite side
  • The centroid divides each median in the ratio 2:1, with the longer segment towards the vertex
4

Applications in Quadrilaterals

  • Section formula helps prove properties of special quadrilaterals
  • Mid-point formula is used to show when diagonals bisect each other
  • Different quadrilaterals have specific properties related to their diagonals
