Abstract Algebra 83: Impossible straight-edge and compass constructions
Abstract: We describe several straight-edge and compass constructions that in general are not possible. These include trisecting an arbitrary angle, squaring a circle, and doubling the cube. In the next video we will touch upon how algebra can be used to prove these constructions are impossible in general.
This video accompanies the class "Introduction to Abstract Algebra" at Colorado State University:
