数学的美体现在它的抽象性,简洁性和规律性,从纷繁的表象中抽象出普遍的规律,并以一种简洁的方式表现出来应用到实际学习中。也可以简化运算,提高准确率,同时激发学习兴趣,感受数学的魅力。本文就是受一道高考题启发,发现了一类几何题的小规律,从而大大简化解题步骤,使解答快捷准确。 The beauty of mathematics is reflected in its abstractness, conciseness, and regularity. It abstracts the universal laws from the complex appearances and presents them in a concise way to practical learning. It also simplifies calculations, improves accuracy, stimulates learning interests, and feels the charm of mathematics. This article was inspired by a college entrance examination question and found a small rule of a class of geometric problems, which greatly simplifies the problem-solving steps and makes the answers quick and accurate.
