nite length, construct Cfl so that it shall be tangent to CD and to the semicircle.A GHB and have a given radius. Suggestion. — Point E may be found by the intersection of twoloci, namely: (1) the locus of centers of circles of given radius andtangent to a given circle ; (2) the locus of centers of… … D Fig. 282. ,335. In Fig. 282 AB and CD are of given lengths. A is the center for thearc HB, B is the center for the arc AG. CD is the perpendicular bisector of thespan AB. EXERCISES 1. Construct the arcs CH and CG tangent to the arcs HB andA G, respectively, and to the line CD at C. 2. Draw lines…
