### Geometric constructions and field extensions

#### Abstract :

Using field extension we will discuss the impossibility of some geometric constructions by ruler and compass e.g. 1. duplicating the cube 2. trisecting an angle 3. squaring a circle. We will start with basic definition and examples required for this. Prerequisites: definition of a field.
