Overview
Co-ordinate geometry is a branch of mathematics that combines algebra and geometry to solve problems using coordinates. This chapter introduces fundamental concepts like distance formula, section formula, and slope of a line, which help us find distances, divide line segments, and understand the inc
Key Concepts
The distance between two points A(x₁
The distance between two points A(x₁, y₁) and B(x₂, y₂) is calculated using the formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]. This formula is derived using
When a point P divides
When a point P divides the line segment joining points A(x₁, y₁) and B(x₂, y₂) in the ratio m:n, the coordinates of P are: P = [(mx₂ + nx₁)/(m + n), (
The midpoint of a line segment
The midpoint of a line segment joining points A(x₁, y₁) and B(x₂, y₂) has coordinates: M = [(x₁ + x₂)/2, (y₁ + y₂)/2]. This is a special case of secti
The centroid of a triangle
The centroid of a triangle with vertices A(x₁, y₁), B(x₂, y₂), and C(x₃, y₃) has coordinates: G = [(x₁ + x₂ + x₃)/3, (y₁ + y₂ + y₃)/3]. The centroid d
The slope of a line passing
The slope of a line passing through points (x₁, y₁) and (x₂, y₂) is m = (y₂ - y₁)/(x₂ - x₁). It represents the rate of change of y with respect to x a
