## What is Pythagoras Interactive?

Eureka! An interactive illustration of the Pythagorean Theorem. Drag the legs of the right triangle and watch the three squares transform in real time. Every side shows its length, every square its area — in radical form when needed, so you'll see 2√2 rather than 2.828.

Slide through a visual demonstration of Euclid's original proof from Book I of the Elements. Understand why the theorem is always true, not just what it claims.

## Key features

- Interactive triangle manipulation
- Visual representation of squares on sides
- Real-time updates to hypotenuse and areas
- Radical form for distances
- Clear labeling of sides and areas
