How it's used
Mathematical terminology in Hong Kong schools often uses specific characters that mirror formal geometry definitions. While students learn these terms in a classroom setting, they are rarely used outside of academic or technical discussions. It is strictly a geometric classification rather than a term with metaphorical or slang applications.
