I have made a few small amendments to my answer to part one of this exercise, which I hope will make my answer clearer. Vasco/Admin Vasco, The presentation is very clear. Rereading provokes a couple of new thoughts. In the last (or second to last) paragraph of p. 1, the sentence finishes “since they lie on the intersection of two planes.” It would be good to expand that because one's first thought is that you mean the intersection of $\mathbb{C}$ and $C$, but that would not be right. I think you mean the intersection of $C$ and the plane of the rays through the collinear points on $\mathbb{C}$. In the last paragraph, you have “Since the angles between the light rays passing through the points $a^\prime,\ b^\prime,\ c^\prime,\ d^\prime$ are the same as those passing through $a,\ b,\ c,\ d$”. One could also write this “Since the four rays passing through the points $a^\prime,\ b^\prime,\ c^\prime,\ d^\prime$ are the same as those passing through $a,\ b,\ c,\ d$, the angles between them are unchanged, so we can write …” Gary |

I will think about how to write this to avoid confusion and repost. Thanks.
