The technique for making a six-petalled rosette is illustrated: Begin by drawing a circle; next, without adjusting the compass, put the point of the compass anywhere on the circle and make a second circle of the same size; now place the compass point on the intersection of the two circles and draw another circle; after six repetitions, the design looks like the second-to-last drawing; in the final drawing the shaded areas show the finished petal decoration. Rosettes are another example of classical design in which 60-degree angles can be found.
