Shyt, reread the post you quoted from please.
It was you that was confused about triangles in the first place.
Embarrassed about being caught out about the detail of the LHR triangle and now trying in vain to dig yourself out by any chance!
Bigging myself up! Far from it, just getting the facts right.
Thing is, I know my place, as lowly as it may be to you, while you keep having to tell us yours.
