## Ceva, Giovanni (1647–1734)Jesuit-trained Italian mathematician who specialized in geometry. His greatest discovery, now known as Ceva's theorem, can
be stated as follows. Given a triangle with vertices (corners), A,
B, and C and points D, E, and F
on the opposite sides, the lines AD, BE, and CF
will intersect at a single point if BD × CE ×
AF = DC × EA × FB. The term Cevian line was coined by French geometers around
the end of the 18th century to honor Ceva. It is defined as any line joining
a vertex of a triangle to a point on the
opposite side. The median, altitude,
and angle bisector are all examples of Cevians. The perpendicular bisector,
however, in most cases, is not a Cevian because it doesn't usually pass
through a vertex. ## Related category• MATHEMATICIANS | |||||
