Straightedge and Compass Constructions by Molly Siebecker '17
Wednesday, February 15 at 1:00pm to 1:45pm
Abstract: Any arbitrary angle can be bisected using only an unmarked straightedge and a compass; it is not possible, however, to trisect an angle with these tools alone. Using this example, this colloquium will show how, by converting the geometric steps used in constructions made with a straightedge and compass into algebraic form, extension fields can be used to determine whether a given length or angle is constructible.
