An oblong is a figure whose opposite sides are equal andparallel, and whose angles are right angles. The drawing of the oblong diders little from that of thesquare, care being required only to distinguish the Fig. 20. Example 1.—Draw an oblong 3 x 2^ lying on , J , side 3, parallel to^ and 2 within it; oblong to be i toright. Specifications as before. 38 DRAWING. Construct figure as before. Find M, and measure off AC 4= (distance to right), CD = 3^ (length of side), and measure offBE 2 (breadth); measure off BC=:2 (distance within ).Join EM, BM, C , D ; through H, F draw HK, FGparallel to CD, meeting D in G, K : then FK will beoblong required. For FG = HK = CD = 3, GK = FH = EB =2, and HC = CB = 2. (Fig. 20.) Exercise V. (H = 6, = 4, scale ^ = T.) 1. Draw an oblong 4 x 2 _]_ to , and 4 to left, J_ and 3 within it; oblong to rest on end. 2. Draw an oblong 7 x 5, standing on end on , parallelwith and 2 within it, directly in front. 3. Draw an oblong 3 6 x 4 6\ parallel to and 2 6above it, right corner 3 6^ to left;
