## 11/22 -- High School II: Nonclassical Constructions - Poncelet Steiner (Christopher Ohrt)First proven by Steiner in 1833, every geometric construction with a compass and straightedge can be accomplished using a straightedge alone, as long as a single circle and its center are given. In this session, we will find the constructions that establish the Poncelet-Steiner Theorem. ## Handouts: |
