geometry.setTrianglePosition找不到符号

public class Example5_6{ public static void main(String args[]){ Square sq=new Square(); Triangle trian=new Triangle(); Geometry geometry; geometry=new Geometry(sq,trian); geometry.setSquareposition(50); geometry.setSquareEdge(90); geometry.setTrianglePosition(130,60,70); geometry.setTriangleEdge1AndEdge2AndEdge3(40,50,60); System.out.print("几何图形中正方形和三角形的位置关系是:"); geometry.showState(); System.out.println("几何图形重新调整了正方形与三角形的位置"); geometry.setSquarePosition(90); geometry.setTrianglePosition(120,50,60); System.out.print("调整后，几何图形中正方形和三角形的位置关系是:"); geometry.showState(); }}

geometry这个类呢，代码格式化一下。
