The curved line extending from a to h inthis figure represents the development of the central line of the planwreath, and, as shown, it rests on an oblique plane inclining to oneside only—namely, to the side ofthe plan tangent a. The jointsare made square to the devel-oped tangents a and m of the in-clined plane; it is for thispurpose only that tangents aremade use of in wreath construc-tion. They are shown in thefigure to consist of two lines,a and m, which are two adjoiningsides of a developed section (in ^ig. ge. semicircular Fig. 85. Acute-Angle Plan. Joint
