如何从复杂图形中找出我们需要的信息,是几何证明或计算必须要解决的一个问题.对于一些复杂图形,如果你有目的地查找,针对性比较强,你就可以排除大量干扰,得到与解题相关的有用信息.如有公共端点的两个等边三角形在一起,一定有交叉组合的一对全等三角形,把这一对全等三角形证明出来,就基本能顺势解决相应数学问题.1.模型展示. How to find out the information we need from complex graphics is a problem that must be solved by geometric proof or calculation.For some complex graphics, if you have purposeful search and pertinence, you can get rid of a lot of interference, If you have two equilateral triangles with common ends, there must be a pair of congruent triangles crossing each other. If you prove the congruent triangles, you can basically solve the corresponding math problems with homeopathy. Model display
