Abstract
Very often it is necessary to enlarge and sometimes to reduce mouldings in size but it is also essential to retain their similarity. Figures 134 and 135 show how it is possible to reduce and enlarge irregular figures. Let a – b – c – d – e (figure 134) be an irregular pentagon which has to be reduced in size so that a — b is now a – b′. All the other sides of the figure are to be reduced proportionately.
