尺规绘图的基本流程
English response:
The basic process of compass and straightedge construction, also known as geometric construction or Euclidean construction, involves using only a compass and an unmarked straightedge (i.e. a ruler without any measurement markings) to create various geometric shapes and figures. The process typically involves the following steps:
1. Use the compass to draw two points that will serve as the endpoints of the line or the vertices of the angle you want to construct.
2. Place the compass point on one of the points and adjust the compass width to the desired length for the line segment or the radius for the circle.
3. With the compass width set, draw an arc that
intersects the other point to create the line segment or the circle.
4. To construct a perpendicular or parallel line, use the compass to create congruent segments or arcs, and then connect the points where they intersect.
5. To bisect a line segment or an angle, use the compass to create congruent arcs centered at each endpoint or vertex, and then draw a line connecting the intersections of the arcs.
These are just a few examples of the basic steps involved in compass and straightedge construction. The process can be used to create a wide range of geometric constructions, including equilateral triangles, regular polygons, and more complex figures.

尺规绘图的基本流程，也称为几何构图或欧几里德构图，涉及使用指南针和无标记直尺（即没有任何测量标记的尺子）来创建各
种几何形状和图形。

该过程通常包括以下步骤：
1. 使用指南针绘制两个点，这些点将用作线段的端点或要构造
的角的顶点。

2. 将指南针的尖端放在一个点上，并调整指南针的宽度，以便
绘制线段的所需长度或圆的半径。

3. 设置好指南针的宽度后，绘制一个与另一个点相交的圆弧，
从而创建线段或圆。

4. 要构造垂直线或平行线，使用指南针创建相等的线段或圆弧，然后连接它们相交的点。

5. 要平分线段或角，使用指南针在每个端点或顶点处创建相等
的圆弧，然后绘制连接圆弧相交点的线。

这些只是尺规绘图中涉及的基本步骤的几个示例。

该过程可用
于创建各种几何构图，包括等边三角形、正多边形和更复杂的图形。
