Thomas Ceva

Ceva, THOMAS, mathematician, b. at Milan, December 21, 1648; d. there, February 23, 1737. In 1663 he entered the Society of Jesus. He was a prolific writer on a variety of subjects, especially mathematics and poetry. He is known today only for the theorem in geometry which bears his name. Ceva’s Theorem is: three concurrent lines drawn through the vertices of a triangle divide the opposite sides so that the product of the three distanceratios is equal to unity. Ceva published this important proposition in 167g. It is the dual of the theorem of Menelaus.
