Overview

The Cartesian System of Coordinates is a fundamental concept in coordinate geometry that bridges the gap between algebra and geometry. Named after René Descartes, this system allows us to represent points in a plane using ordered pairs of numbers, enabling us to solve geometric problems using algebr

Key Concepts

A system consisting of two perpendicular

A system consisting of two perpendicular lines (x-axis and y-axis) intersecting at origin O(0,0), dividing the plane into four quadrants. Any point P

Distance between points P₁(x₁

Distance between points P₁(x₁,y₁) and P₂(x₂,y₂) = √[(x₂-x₁)² + (y₂-y₁)²]. Step-by-step approach: 1) Identify coordinates, 2) Find differences (x₂-x₁)

Internal division

Internal division: Point dividing line segment joining (x₁,y₁) and (x₂,y₂) in ratio m:n is ((mx₂+nx₁)/(m+n), (my₂+ny₁)/(m+n)). External division: ((mx

Area = ½|x₁(y₂

Area = ½|x₁(y₂-y₃) + x₂(y₃-y₁) + x₃(y₁-y₂)| or using determinant form. Step-by-step method: 1) Write coordinates in order, 2) Apply formula systematic

Slope m = tan θ =

Slope m = tan θ = (y₂-y₁)/(x₂-x₁). Parallel lines: m₁ = m₂. Perpendicular lines: m₁ × m₂ = -1. Problem-solving approach: 1) Calculate slopes, 2) Apply

Learning Objectives
