📍 Coordinate Geometry
Drag the two points
and watch the distance & midpoint update — see the formulas come alive!
Points

Distance AB
√[(x₂−x₁)² + (y₂−y₁)²]

🧠 The Big Idea
Every point on the plane has an address
(x, y)
. Geometry becomes algebra!
Distance formula:
AB = √[(x₂−x₁)² + (y₂−y₁)²] — it's just Pythagoras in disguise. 📐
Midpoint
is the average of the coordinates. The
section formula
extends this to any ratio.
