全等三角形的判定方法有 SAS、ASA、AAS、SSS 共4种,其中每一种方法都有3个条件.全等三角形的性质有对应角相等、对应边相等.因而,无论是从三角形全等的判定条件,还是从应用全等三角形的性质都可以设计探索问题,常见的探索性问题有:(1)探索三角形全等的条件;(2)探索三角形全等的结论;(3)探索三角形全等的条件和结论.在解答探索问题时,首先从题中找到已知条件、隐含条件和可证出的条件,然后利用三角形全等的判定条件来寻找缺少的条件即可解决问题.
There are four methods for determining congruent triangles: SAS, ASA, AAS, and SSS. Each of these methods has three conditions. The properties of congruent triangles have equivalent angles and equal sides. Therefore, whether it is from a triangle Judgment conditions, such as from the application of congruent triangles, can be explored and explored. Common exploratory problems are: (1) to explore the condition of the triangle congruent; (2) to explore the congruence of the triangle; (3) to explore The conditions and conclusions of the triangle congruence. When solving the problem, first find the known conditions, implicit conditions and verifiable conditions from the problem. Then use the trigonometric conditions to find the missing conditions to solve the problem. .
