Compass-Only Geometric Constructions by Alejandro Saldivar
In the geometry of straightedge and compass constructions, it turns out that the straightedge is not necessary. This math seminar will cover the following: a bit of history involving compass-only geometry why a collapsible compass is sufficient some examples of constructions with just a compass at least one reason why the straightedge is superfluous in the geometry of straightedge and compass
