用尺规作图三等分任意角号称几何三大难题之一,它已被证明是不可能的.这说明圆弧不可能用尺规作图任意等分.因为三等分任意角与三等分任意圆弧实质上是一回事儿.但这并不能说明圆的面积不可能用尺规作图任意等分. One of the three major geometries of geometry is to use the ruler to plot any of the three corners. It has been shown to be impossible. This means that arcs cannot be arbitrarily divided by a ruler. Triangulation of any angle and three Dividing arbitrary arcs is essentially one thing. But this does not mean that the area of ​​a circle cannot be equally divided by a ruler.
