　　几何画板作为一款专业且强大的几何绘图软件，无论是简单，还是复杂的几何图形，使用它都可以轻松绘制出来，如摩莱三角形这种特殊的几何图形，使用几何画板绘制只需4步即可绘制完成。那么，几何画板怎么画摩莱三角形呢？下面，我们就一起往下看看吧！

　　方法步骤

　　1、画带角的三等分线的△ABC

　　选择自定义工具——角工具——加角的三等分线，在工作区域任意画一个带内角三等分线的角，然后用线段工具将相连两个点连接起来，这样就得到了△ABC。

　　然后继续使用上面的自定义工具，然后依次点击点C、A、C，就会出现∠CAB的三等分线；同样地，画出∠BCA的三等分线。

　　2、画出交点D、E、F

　　选择移动工具，分别点击与BC、CA、AB相邻的每两线的交点，记为点D、E、F，如下图所示。

　　3、构造△DEF

　　使用线段直尺工具，分别连接DE、EF、FD，这样就得到了△DEF，而且这个三角形是正三角形。
