Olympic triangle be perfectly sharp, either, since it is a course. Traditionally the configuration of the triangle is an equilateral triangle (3 equal sides and 3 equal angles of 60 degrees) with a ratio of the windward leg to a reaching leg being 1:1. In that case the course length for the 9 legs described above is 9 times the length of the windward leg. The angle at each point of the triangle is 60 degrees. The windward leg is generally aligned with the average wind direction. Another configuration is a triangle with a right angle at the wing mark and 45
Schwarz triangle function a vertex of the polygon "P" makes an angle of less than 2/3 with each of the edges of the polygon at that vertex if exactly two triangles of "P" meet at the vertex, since each has an angle less than or equal to /3 at that vertex. To check this is true when three triangles of "P" meet at the vertex, "C" say, suppose that the middle triangle has its base on a side "AB" of "P". By induction the radii "OA" and "OB" makes angles of less than or equal to 2/3 with the edge "AB". In this
