ABSTRACT:
Flooring and/or tiling having golden arabesque designs are made up primarily of three pieces. First, there is a square whose sides will have common "a" measurements. Secondly, there is a rectangle whose larger side will measure "a" long and whose shorter side will be "a.sqroot.2-a", obtained as the difference between the diagonal of the square having "a" sides and the proper "a" side. The third piece is a rectangle whose larger side will be "a" long and whose lower side will be ##EQU1## obtained as the difference between the half of the square "2" and the lesser side of the second rectangle "a.sqroot.2-a," "a" being any real number. The first piece or square has its diagonal line marked while the second piece, or principal rectangular piece, has an arc with a radius of "a.sqroot.2" drawn from vertex to vertex.
