A circle or curved line that passes through all five vertices of a pentagon.
From Latin circum- (around) + pentagon (five-sided polygon), combining geometric terminology to describe circumscribed circles around five-sided figures.
Every perfect pentagon can have a circle drawn through all its corners—mathematicians call this the circumcircle, and it's one of the basic building blocks of classical geometry that ancient Greeks obsessed over.
