Line intersecting both a vertex and opposite edge of a triangle
In geometry, a cevian is a line segment which joins a vertex of a triangle to a point on the opposite side of the triangle.[1][2] Medians and angle bisectors are special cases of cevians. The name "cevian" comes from the Italian mathematician Giovanni Ceva, who proved a well-known theorem about cevians which also bears his name.[3]
