在我们学习了多边形的内角和是(n-2)·180°后,课本上由此又推出了“任意多边形的外角和都等于360°”的结论.我发现,这个结论说明多边形的外角和与多边形的边数n无关,是一个固定不变的量360°.
After we learned about the interior angle of the polygon and (n-2) · 180°, the textbook thus introduced the conclusion that the “external angles of arbitrary polygons are equal to 360°”. I found that this conclusion illustrates the polygon’s The outer angle is independent of the number of edges n of the polygon and is a fixed amount of 360°.
