Overview

Co-ordinate Geometry is a fundamental branch of mathematics that combines algebra and geometry to locate points in a plane using ordered pairs of numbers. Developed by René Descartes, this system allows us to find distances between points, divide line segments in given ratios, and locate centroids o

Key Concepts

The coordinate plane consists of two

The coordinate plane consists of two perpendicular axes - x-axis (horizontal) and y-axis (vertical) intersecting at origin O(0,0). Any point P is repr

The distance between two points P(x₁

The distance between two points P(x₁,y₁) and Q(x₂,y₂) is calculated using: d = √[(x₂-x₁)² + (y₂-y₁)²]. This formula is derived from the Pythagorean th

When point P divides line segment

When point P divides line segment AB joining A(x₁,y₁) and B(x₂,y₂) internally in ratio m:n, the coordinates are: P = ((mx₂+nx₁)/(m+n), (my₂+ny₁)/(m+n)

The midpoint of line segment joining

The midpoint of line segment joining A(x₁,y₁) and B(x₂,y₂) is calculated as: M = ((x₁+x₂)/2, (y₁+y₂)/2). This is a special case of section formula whe

The centroid of triangle with vertices

The centroid of triangle with vertices A(x₁,y₁), B(x₂,y₂), C(x₃,y₃) is G = ((x₁+x₂+x₃)/3, (y₁+y₂+y₃)/3). The centroid is the point where all three med
