  2. On Menelaus Menelaus was a mathematician who lived during the Roman Empire in both Alexandria and Rome. His work was largely on the geometry of spheres. This theorem was first discussed in his book, Sphaerica, and later mentioned by Ptolemy in his work Almagest. It achieved wider familiarity when the 17th century Italian mathematician Giovanni Ceva expanded upon it in his theorem on the same subject. Menelaus’ Theorem proves that spheres are made up of spherical triangles. example of a spherical triangle example of a geodesic

  3. Basic Concepts of the Menelaus Theory Given a triangle ABC, and a transversal line that crosses BC, AC and AB at points D,E and F respectively, with D,E and F distinct from A,B and C .
