In geometry, a line segment in a triangle connecting a vertex to a point on the opposite side.
Named after the Italian mathematician Giovanni Ceva (1647-1734), who discovered properties of these lines. The suffix '-ian' indicates it's named after a person.
Cevians are the foundation of beautiful geometric theorems—Ceva's Theorem states that three cevians intersect at a single point if and only if certain ratios multiply to equal one, which feels like magic!
