#2That's pretty funny. Like the author said, it may not be true, but it's a fun piece of analysis.
I can almost remember doing math like this at school.

#3Thanks for kind comments. Yes, it was meant as a little light hearted fun. I've been writing a series of articles about solids inscribed inside others, and this seemed a (stretched) way of giving the article a different spin.

#4Actually Δ ADE is not a right triangle. (Unless A is infinitely far away from D and E.)
Edit: thanks TheLoneWolfling, I was looking at the wrong angle.

Err, are you sure about that? It touches at one point, so that makes it a tangent, so it's perpendicular to the circle. I think it it a right angle.
(This is the internet, so I'm sure there will shortly be lots of posts of: Yes it is, no it isn't, and we'll find out for sure).

Wrong.
The angle ADE is a right angle, as AD is tangential to the sphere. Hence, Δ ADE is a right triangle.
I'm assuming your mistake was thinking that it was AED that was the right angle, not ADE.
