类比推理是根据两个对象有一部分属性类似,推出这两个对象其他属性亦类似的一种推理方法,是由特殊到特殊的推理.类比推理的一般步骤是:先找出两类对象之间可以确切表达的相似性(一致性);再用一类对象的性质去推测另一类对象的性质,从而得出一个猜想;最后验证猜想,但类比推理的结论不一定正确.一、性质类比例1平面几何中有如下性质:如图1,设O是等腰Rt△ABC底边BC的中点,AB=1,
Analogical reasoning is based on the fact that two objects have similar attributes, and deducing other properties of the two objects is similar to a kind of reasoning method, which is from special to special inference. The general steps of analogical reasoning are as follows: Can express the exact similarity (consistency); then the nature of a class of objects to speculate on the nature of another type of object, which leads to a conjecture; the final guess conjecture, but the conclusions of analogical reasoning is not necessarily correct. Proportional 1 Plane geometry has the following properties: As shown in Figure 1, let O be the midpoint of the isosceles Rt △ ABC base BC, AB = 1,
