Applying 19th-century Algebra to Ancient Problems of Geometry

Ruslan Muslumov

 

 

Abstract: The Greek mathematicians were fascinated by geometrical constructions. Using only an unmarked ruler and a pair of compasses, they bisected angles, trisected line segments, and constructed squares with the same area as a given polygon. But there were three types of construction that defeated them:

1. Doubling a cube,

2. Trisecting an angle,

3. Squaring the circle.

These problems all date from the 4th-century B.C., and throughout the next two millennia valid constructions were sought without success.

I will try to sketch how the 19th-century hapless French mathematician Galois work is the fundamental tool to be able to give the proper answer to these questions.
