lines as shown in the sample dotted line from E to K. Proceed thus to make the six divisions of the drawing.
To Draw a Square. To
make an absolutely accurate quadrangle proceed as follows: Describe a circle as in Fig. i. Bisect it through its center at A to XX. Make a segment of an arc, CC, by placing the point of the compass at X at the left. The line BB is made the same way from X at the right. A vertical line prolonged through the circle from the intersection of the lines BB and CC and intersecting the horizontal line at A, and continued to the base of the circle, completes four right angles.
On the same drawing (Figs. i and 2 being in reality a single drawing, but, for the sake of plainness, is made in two diagrams) describe arcs of circles of the same size or circumference, by placing the point of the compass at each X. The segments meet or intersect at EEEE. They also meet the circumference of the original circle at OOOO, but this has nothing to do with making the quadrangle or square. Now extend four lines from each E to the other and they will touch the circle at each X. A perfect square is formed by these four lines.
Other Forms Produced by This Operation To Make a Hexagon.
Draw lines as shown at the left of the diagram (Fig. 2) (starting from below) from O, X, O, O, in the dotted lines, proceeding of course all the way around.
To Make an Octagon. Extend the lines from each E to the center at A (Fig. 2). Now make eight lines as shown by the dotted line X to F, which gives one section of an octagon.
To Make an Equilateral Triangle. A triangle having all sides of an equal length draw a line GG parallel to XX at the top of the circle. Extend lines from the center A through the OO's (as produced in Fig. 2) to the line GG, and an equilateral is shown in the heavy lines as a result.
