Pythagorean theorem

The interactive animation shows the squares formed by the cathets and the hypothenuse of a right-angled triangle.

You can move the blue dot interactively with the mouse.

The animation was developed as a offline application for Windows and Macintosh systems and for integration into Microsoft PowerPoint slides. The online version presented here serves as a preview. The exe or app file can be downloaded free of charge in the member area.



The point A of the triangle can be moved interactively along the circumcircle. All of the squares shown are continuous in real-time.
