Coordinate Geometry – Notes
Distance Formula
The distance between the points (x1y1) and (x2,y2) is given by :
The distance of the point (x, y) from origin is given by :
Three points A, B and C are collinear if AB + BC = AC
Section Formula
The section formula states that any point P(x, y) that divides a line segment in the ratio m:n can be represented as ( )
The following are the corollaries f the section formula :
- The midpoint of a line segment joining (x1, y1) and (x2, y2) is: ( , )
- The centroid G of a triangle, with vertices ( ), ( and ( is: ( , )
