我对尺规作图很感兴趣,经常绘制几何图形,从中得到不少乐趣,也时有发现,下面就是其中一个: 三角形中,如果一个角的角平分线与这个角对边的垂直平分线只有一个交点,那么这个交点一定在三角形外. I am very interested in the ruler drawing. I often draw geometric shapes and get a lot of fun. I have found it too often. Here’s one of them: In a triangle, if the angle bisector of a corner and the perpendicular bisector of this corner are perpendicular to each other There is only one intersection, then this intersection must be outside the triangle.
