### 通过画平行四边形与梯形的方式来了解顶点属性 ###

先画出四边形

上图是以前视图为视角的

通过改变矩形最上边两个顶点的方法形成平行四边形

首先调出图形的编辑样条线

然后选择顶点

这样就可以选中并操作四边形的顶点了

选中四边形最上边两个顶点，然后拖动，得到如下效果

四边形的两条边是曲线，现在将弯曲的线段变为直线

选中整个四边形，然后右键，可以调出菜单

选中途中红框中的不同选项可以展示不同的效果

选择角点就可以形成平行四边形

画梯形也是类似的，画出矩形之后选择“分段”

然后选中要改变的线段

将线段进行缩放，得到如下效果

将右侧的选中项改为“顶点”

选中所有顶点，右键调出菜单，选择“角点”
