"WebJan 31, 2011 · I'm not sure what Hartshorne has in mind, but Pappus' theorem is a simple consequence of similarity of Euclidean triangles (in guise of the intercept theorem) and there's no need of introducing the circle: Let $P$ be the point of intersection of $l$ and $m$. All we need to do is to show that $\frac {PA'} {PB} = \frac {PB'} {PA}$. " - Pappus’s theorem
