I'm not so sure about that. It looks like the primary meaning of that codepoint is "increment operator", used for small discrete changes, which usually is an actual Delta (and read as such aloud). Visually, it also shows the same typographic weight changes as is common with Delta that are absent in the white triangle symbol.
As for using the triangle symbol for geometry, well let's just say that's a conversation for another day. On Sun, Apr 26, 2020 at 10:12 PM Thierry Arnoux <[email protected]> wrote: > You’re right!
