Ceva's theorem wikipedia
WebCeva's theorem provides a unifying concept for several apparently unrelated results. The theorem states that, in three Cevians and are concurrent iff the following identity holds: The theorem has a less known trigonometric form or The latter may serve as a source of great many trigonometric identities - some obvious, some much less so.
