Every square, rectangle, parallelogram, rhombus, or triangle is rep-4. Either diagonal of a rhombus divides it into two congruent isosceles triangles. A parallelogram with sides of equal length (equilateral) is a rhombus but not a rhomboid. From its diagonal vectors it creates shapes of the cross, rhombus and the trapezoid. Each diagonal of a rhombus bisects opposite angles. A golden rhombus is a rhombus whose diagonals are in the golden ratio. A rhombus with right angles is a square. It consists of a blue cloth with a horizontal white rhombus. These include the square, the rhombus, and the kite. The rhombus tiling was independently discovered by Robert Ammann in 1976. These had solid supports called rhombus seat supports. A rhombus so obtained is called a "golden rhombus". Fuka decided to use all these levels with exception of one containing a rhombus. Although becoming infamous for his ride on Spinning Rhombus at Barcelona. They chose "Port Rhombus" and "The Tide".
