《中小学数学》初中版2008年第4期刊发了令标的《对一道平几竞赛题的多方探析》,该文对2007年北京市中学生数学竞赛初二年级试题的第四题进行多角度探析,研读后颇有感悟.笔者通过观察与探讨,在令标老师研究的基础上,运用其他方法再对该题进行了研究. The fourth issue of “Mathematics in Elementary and Secondary Mathematics” junior middle school in 2008 issued the “Multi-Study on the Competition Problem of a Ping-Ji-Chang Competition”. This article analyzes the fourth problem of the second-grade mathematics test questions of the Beijing Junior High School Mathematics Competition in 2007. After studying it, I was quite sensible. Through observation and discussion, the author studied the subject on the basis of research made by the subject and used other methods to study the subject.
