"Typo in Compass Alone"
|
This is a great site, full of interesting and stimulating ideas. In Do You Know? -- Geometric Construction with the Compass Alone -- Problem 7 -- Solution, the author provides an answer that does not use "graphic means" (no diagram). After drawing my own diagram, I seem to detect a typo in the Proof section: "By construction, the points C, E and O are collinear (lie on the same straight line.)" This should be: "By construction, the points C, D and O are collinear (lie on the same straight line.)" |

You are right. I fixed the typo. Many, many thanks. Alex
