Can you find the missing distance in this rectangle? 🤔
Welcome to Visual Maths Lab 010 by AzuCATion.
A point (P) lies inside a rectangle. Its distances from three vertices are 5, 10 and 13. Can you find the distance from (P) to the fourth vertex?
This question introduces a beautiful and highly useful geometry result — the British Flag Theorem.
But instead of simply memorising a formula, watch how the relationship develops visually and how the entire calculation transforms smoothly to the final result.
