①分别连接OA,OB,OC,OD,OE;②分别在AO,BO,CO,DO,OE上截取OA′,OB′,OC′,OD′,OE′,使OA′OA=OB′OB=OC′OC=OD′OD=OE′OE=13;③顺次连接A′B′,B′C′,C′D′,D′E′,E′A′.五边形A′B′C′D′E′就是所求作的五边形;(3)画法如下:①分别连接AO,BO,CO,DO,EO,FO并延长;②分别在AO,BO,CO,DO,EO,FO的延长线上截取OA′,OB′,OC′,OD′,OE′,OF′,使OA′OA=OB′OB=OC′OC=OD′OD=OE′OE=OF′OF=12;③顺次连接A′B′,B′C′,C′D′,D′E′,E′F′,F′A′.六边形A′B′C′D′E′F′就是所求作的六边形.方法总结:(1)画位似图形时,要注意相似比,即分清楚是已知原图与新图的相似比,还是新图与原图的相似比.(2)画位似图形的关键是画出图形中顶点的对应点.画图的方法大致有两种:一是每对对应点都在位似中心的同侧;二是每对对应点都在位似中心的两侧.(3)若没有指定位似中心的位置,则画图时位似中心的取法有多种,对画图而言,以多边形的一个顶点为位似中心时,画图最简便.三、板书设计
