Fig. 70. Let AB be the given line and C the external point; at anypoint B and distance BC describe an arc to cut AB; with Cas centre and CB as distance describe an arc, and with B ascentre and distance equal to AC describe an arc cuttingformer arc in D ; join CD, which will be parallel to AB.(Fig.… … Let AB be the given line ; draw DE parallel to AB oneither side, and on this line set off the required number of GEOMETRICAL DRAWING. 109 equal distances (in this case five); then join each point ofsection with A, which will divide AB into the same numberof equal parts. (Fig. 71.) (c) To divide a…
