Coordinate Geometry EP2 | Distance Between Two Points | Distance Formula & Pythagoras | MathExam

Coordinate Geometry EP2 — Distance Between Two Points How do we find the distance between two points on a coordinate plane? In this episode of MathExam, we build the distance formula step by step from horizontal and vertical distances, then use Pythagoras’ theorem to derive d = √[(x₂ − x₁)² + (y₂ − y₁)²] You’ll learn how to: • find horizontal and vertical distances • form a right-angled triangle between two points • derive the distance formula using Pythagoras’ theorem • substitute coordinates correctly • work with negative coordinates • understand why the order of the two points does not affect the distance • avoid common mistakes • solve an exam-style practice question Suitable for students studying Coordinate Geometry for GCSE, GCE and HKDSE Mathematics.
