Questions & Answers

Q: What did Hippocrates contribute to mathematics?

Hippocrates expanded on Pythagoras' theorem by proving that any similar shape on the hypotenuse of a right-angled triangle will have the same area as the shapes on the other two sides.

Q: What is a lune?

A lune is a curve that represents the area of the shapes on the sides of a right-angled triangle. Hippocrates used lunes to demonstrate the equal areas of different shapes within triangles.

Q: How did Hippocrates prove the equal areas of lunes and triangles?

He drew various examples of triangles and their corresponding lunes, showing that the areas of the lunes matched the areas of the triangles. This demonstrated the mathematical relationship between the shapes.

Q: Why did Hippocrates call himself the "loony mathematician"?

Hippocrates referred to himself as the "loony mathematician" due to his unconventional approach to mathematics and his discovery of the equal areas of lunes and triangles, which was groundbreaking at the time.
