垂直于弦的直径平分这条弦,弦的一个端点与圆心的连线构成的直角三角形,就可以应用勾股定理来求解,因此,垂径定理常与勾股定理结伴而行.下面我们仅以近几年的中考题为例来说明. The perpendicular to the diameter of the string bisects the chord, the right triangle formed by the connection of one end of the chord to the center of the circle can be solved using the Pythagorean Theorem, and therefore, the theorem of the dip theorem often goes hand in hand with the Pythagorean Theorem. In recent years, the exam questions as an example to illustrate.
