gle without findingits vertex. * Solution.—Let AB and CD be the given lines. Through any point P, of AB, draw PRparallel to CD (Bk. III. Prob. 6). Bisect theangle BPR by the line PQ, and draw the linePR perpendicular to PQ; bisect PR in S(Bk. III. Prob. 1), and draw SY parallel toPQ. Because CD is… … 14 KEY.
