解数学竞赛题，要善于利用隐含条件，同时注重运用重要的数学思想方法，常能有效地求解．本文就２０００年全国各级初中竞赛题的解法略举数列，以窥一斑．１ 捕捉隐含的特殊三角形或特殊点 几何竞赛题，隐含条件往往较多，对隐含的几何定理、公理、定义、公式等，容易发现，但? Solve mathematics competition problems, must be good at using implicit conditions, while paying attention to the use of important mathematical ideas and methods, often able to effectively solve. This article gives a glimpse of the number of solutions to the national junior high school competitions in 2000. 1 Capture Implicitly Special Triangles or Special Points Geometry contest questions often have more implied conditions. It is easy to find hidden geometric theorems, axioms, definitions, and formulas.
