AB. On tlie given line AB constructa trianole ABF similar to the oiventriangle CDE, by making the anglesat A and B equal at the angles atC and D respectively. Bisect theangles at A and B by lines meetingat G. From G- draw a line parallelto FB till it meets AB at L (Prob.4); and from G draw another… … CHAPTEE XIV peinciples of similitude Peoblem 172. Draw a rectangle ABCD, and join each angle to any pointE. Bisect EB in G, EA in Y, ED in K, and EC in H (Prob. 1).Join FCt, GK, KH, and HF, then FGHK will be a rectanglewith sides one-half the length of the rectangle ABCD. Ifwe draw the diagonals BC…
