类比是数学证明的方法之一.通过两类具有相同或相似特征的现象之间的对比,可以从一类现象的某些已知特征推测出另一类现象相似特征的存在.比如,相似多边形的问题就可以类比相似三角形的问题加以解决.但类比所得出的结论不一定正确,需要进一步证明和检验. Analogy is one of the methods of mathematical proof. By comparing two types of phenomena with the same or similar features, it is possible to infer the existence of similar features of another phenomenon from certain known features of a type of phenomenon. For example, similar polygons. The problem can be solved analogously to the problem of similar triangles. However, the conclusions obtained by analogy are not necessarily correct and need further proof and verification.
