Isn't the base of a cone, just a circle? How would this have "corners"? SDSpivey (talk) 01:41, 3 January 2026 (UTC)

The cone upon which a conic section exists doesn't actually have a base, it's just arbitrarily large (possibly infinitely so) in order for the section to only ever lay along the 'curve' of the cone part.
But, here, the base is wwhere you give up on plotting how far 'down the cone' you go, of the sufficiently large ellipse (or possibly parabolic/hyperbolic curve), which is indeed round but has an sharp (i.e. acute) angle between its flat (and incidentally circular) plane-section and the 'wrapped' pseudo-euclidean plane of the conic-section it intersects with. 92.23.2.208 01:50, 3 January 2026 (UTC)
