    Archimedes of Syracuse

    On the Sphere and the Cylinder in which he determined the volumes and surface areas of spheres and cylinders.
  • 265

    Euclid

    "The Father of Geometry". Wrote the Elements.

    Papus of Alexandria

    States his hexagon theorem and his centroid theorem.
  • 347

    Plato

    His work led to using tools to trisect an angle, to construct a cube twice the volume of a given cube, and to construct a square equal in area to a given circle.

    Hippocrates of Chios

    showed that the ratio of the areas of two circles was equal to the ratio of the squares of their radii.
  • 475

    Pythagoras

    Pythagoras formed a brotherhood. Pythagorean Theorem- The theory states that the sum of the squares of the legs of a right triangle equals the square of the hypotenuse.

    Thales

    Thales brought the science of geometry from Egypt to Greece. Thales studied simliar triangles. Calculated the height of pyramids.
  • Gerard Desargues

    Represented the groundwork for projective geoemetry. This deals with the properites of figures.
  • Period: to

    Rene Descartes

    Combined algebra and geometry to create analytical geometry.
  • Gaspard Monge

    Represented geometric figures on planes and determining distances, angles, and lines of intersection by geometric means.
  • Carl Friedrich Gauss

    Invented non-Euclidian geometry.
  • Hipparchus of Rhodes

    Credited with introducting the division of a circle into 360 degrees into Greek mathematics.
