Two thousand years ago, triangular sails appeared. With proper orientation, these sails could convert wind power from any direction into forward thrust. The sail might be pushed or pulled by the wind force, and the pull was stronger than the push. Although there was no physical understanding of the pulling force, it allowed the boat to sail into the wind.

Which is the best sail form between a form of a Circle or Hexagon or Triangle or a square?
Like all things in life this depends entirely on what you want to use it for. Circles or hexagons, however, would be far too impractical to be of any use due to the number of lines/spars that would be needed to maneuver them. Although that being said, if you wanted to make a sea anchor (like a parachute for the water) they would be the best shapes to use.That leaves us then with triangles and squares.If you want to head up-wind triangle sails are the most common and useful as they are often much easier to maneuver when tacking into the wind. [See http://wiki.answers.com/Q/What_is_tack_in_sailing for the definition of tacking]However if you are traveling down-wind, you typically don't need to change course as often and square sails allow you to catch more of the wind than the triangle sails.Because of their different uses and the ways that they are rigged, triangle sails are typically called "fore and aft" sails, and square sails, are unimaginatively called square sails.As a side note, sometimes quadrangular sails are also used as fore and aft sails (such as a gaff rigged main) and these can have the advantage of catching more wind, however it adds to the complexity of the rigging, as well as the number of people typically needed to raise/douse(lower) them.Anyways, hope that helps!
