THEOREM OF PYHTAGORAS AND GSP FOR GOLDEN RECTANGLE, REGULAR PENTAGON AND QUADRATURE Paul Sexton Buena Park High School psexton@fjuhsd.k12.ca.us Armando M. Martinez-Cruz CSU Fullerton Amartinez-cruz@fullerton.edu Presented at CMC-Palm Springs Nov. 4, 2006
Outline of Presentation • Welcome and Introduction • Pythagoras and Theorem of Pythagoras • Constructions using the theorem: • Golden Rectangle • Regular Pentagon • Pentagon, Hexagon and a Decagon • Quadrature of the Rectangle • Conclusions and Questions
Pythagoras andTheorem of Pythagoras • Bhaskara’s Proof • Garfield’s Proof • Euclid’s Proof • Using Similar Shapes (instead of Squares) on the Sides of the Right Triangle
Constructions using the Theorem • Golden Rectangle • A Square with the Same Area of a Given Rectangle, aka, Quadrature of Rectangle • Pentagon, hexagon and decagon inscribed in the same circle. • Actually, it is possible to construct a triangle with one side of the pentagon, one side of the hexagon, and one side of the decagon. And that triangle happens to be a right triangle. • Some extensions of the Theorem
