Takeany point, as A, in the circumference,and from that point draw the tangentAB; and from the point A, in the lineAB, make the angle BAD=C (pro-blem 5), and AED is the segmentrequired.… … PROBLEM 15. To construct an equilateral triangle on a given finite straight line. Let AB be the given line, and from oneextremity, A, as a center, with a radiusequal to AB, describe an arc. At the otherextremity, B, with the same radius, describeanother arc. From C, where these twoarcs intersect,…
