Giovanni Ceva

Giovanni Ceva (December 7, 1647–June 15, 1734) was an Italian mathematician widely known for proving Ceva's theorem in elementary geometry. His brother, Tommaso Ceva was also a well known poet and mathematician.Ceva received his education at a Jesuit college in Milan. Later in his life, he studied at the University of Pisa, where he subsequently became a professor. In 1686, however, he was designated as the Professor of Mathematics at the University of Mantua and worked there for the rest of his life.Ceva studied geometry for most of his long life. In 1678, he published a now famous theorem on synthetic geometry in a triangle called Ceva’s Theorem. The theorem states that if you have three line segments drawn from the vertices of a triangle to the opposite side, then the three line segments are concurrent if, and only if, the product of the ratios of the newly created line segments on each side of the triangle is one. He published this new theorem in De lineis rectis.
