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… … Fig. 275. parallel to each other, and that BC : GH as 2 :1. If we takeany point L in BD and draw it to point E, it will intersect GKin M, and will divide GK in the same proportion as BD isdivided. On the principle of this problem, we can draw a figure similarto a given figure, and having any…
