The Chinese word document library provides a vast amount of free text, education, learning, policy, reporting and economics word documents. a href = / / a word document Conditions for the congruence of the triangle was chosen from the compulsory education curriculum standard experimental textbook mathematics (human edition). Ii. Teaching objectives Knowledge skill 1. Grasp the ASA and AAS conditions of triangular congruence. 2. Can preliminarily apply ASA and AAS conditions to determine two triangular congruent. Mathematical thinking 1. Make students experience the process of exploring the congruent conditions of triangles, and experience the process of obtaining mathematical conclusions by operation and induction. 2. In the exploration of the triangular congruence and its application process, it is possible to think methodical thinking and make simple reasoning. To solve the problem It will use ASA and AAS conditions to prove that the two triangles are congruent. Emotional attitude 1. Experience the fun of mathematical thinking through exploration and actual process, and arouse the consciousness of applying mathematics. Through cooperation and communication, cultivate the sense of cooperation and experience the joy of success.
