one side of each of the givensquares so as to form a right angle, 2a a b and b c, Fig. 51;connect a c, and, with this line as one side, draw the square,3, which is equal in area to i and 2. The above rule applies to circles as well as squares; ab and b c represent the diameters of the smaller… … agonal, as a b, Fig. 52; then, with the length of the sideas radius and a b 2iS centres, strike the arcs intersecting atc and d; then connect a c, c b, b d and d a, which gives thedesired rhombus.
