在我校九年级的一次数学月考中,有一道选择题如下:点P是△ABC中边AB上的一点,过点P作直线(不与直线AB重合)截△ABC,使截得的三角形与原三角形相似,满足这样条件的直线最多有().A.2条B.3条C.4条D.5条笔者上网查询得知,该题来源于2002年北京市东城区的一道中考题,其答案为(C).而且从网上还能查到该题的常见解法:先画出△ABC及其边AB上的一点尸(注:仔细分析后不难发现,这时△ABC的形状及点P在边AB上的位置,都是解题者根据得出答案(C)的需
In my ninth grade mathematics month test, there is a multiple choice question is as follows: point P is △ ABC in the middle of a point AB, P point for a straight line (not coincident with a straight line AB) cut △ ABC, Triangles and the original triangle similar to meet the conditions of the line at most () .A.2 Article B.3 Article C.4 Article D.5 The author online query that the title from the 2002 Beijing Dongcheng District, a In the examination questions, the answer is (C). And from the Internet can also find a common solution to the problem: first draw △ ABC and its side AB on a little corpse (Note: careful analysis is not difficult to find, then △ ABC The shape and the position of the point P on the side AB are solved by the solver according to the answer (C)
