- quadrature: inscribing of rotated squares within the framing square. Having established the basic square abcd in step one, for example, he explains the next step as follows: “Divide the distance from a to b into two equal parts, and mark an e at the midpoint. Do the same from b to d and mark an h; from d to c and mark an f; from c to a and mark a g. Then draw lines from e to h, h to f, f to g, and g to e, as in the example of the figure drawn hereafter.
